Having trouble with bleed settings

Question

Hello,
I'm trying to make an image a full bleed on an 8.5x11 page. I've got the "Use Document Bleed Settings" checkbox selected in the Bleed and Slug panel of the Marks and Bleeds setting in the PDF export. However, I'm getting this blanking area and then a thin duplication of the image on the verso page. Also, there's a white gutter area. When I deselect the check box, the image seems to look correct on the page. However, I'm concerned that if the checkbox isn't selected, something else might not print properly.
I've also got some images that cross from one page to another. With the box checked, the image doesn't split correctly but there's a small duplication on the other page, suggesting the image won't print up properly. I don't mind that some of the image disappears into the gutter/spine, it's part of the look. But I don't want a white stripe & thin slice or replicated part of the image on the opposing page.
Does anyone have a suggestion of how to handle this properly?
Thank you!

I'm using ID 8.0.1 in Mac OS 10.9.
I get the white stripe when I place a full image covering the outer edge bleeds and abuting right against the inner edge or spine. But when I put an image across the spine and onto the other page, I get the slightly duplicated image as can be seen in the animal horn.
When I use Salah Fadlabi's suggestion of unchecking "Use Document Bleed Settings" and then changing the "Inside" bleed to 0in while leaving Top, Bottom and Outside to 0.125in, The image looks correct when I look at a 2-up view, it doesn't get split or have the weird white line.
rajsre's suggestion that when the paper is cut, the repeated image with the animal horn will actually look correct. However, I'm not confident how this will play out, as I get the white stripe in the single-page images. I didn't do any special setup like "space between", as I'm not sure where that setting is. Sorry, I'm still learning. When I Export, I'm not doing anything special. I know a little bit of the image will be eaten by the gutter, especially with the images that go across the pages.
My printer (Ingramspark) has this to say about gutter margin:
• GUTTER MARGIN:
SADDLE STITCH BOOKS: no gutter margin required; items can be taken completely to the bind edge.
PERFECT / CASE LAMINATE / DUST JACKET BOOKS : 0.125" (3 mm) gutter margin (no-ink area) required on the bind side of the interior. These are bound with glue, and the area is designated so it can adhere to all pages (see reference templates for example). Crossover spreads (images/color intended to straddle a spread) may be used as long as the gutter margin is placed in between where the images/color would normally meet.
Blue (Bleed) Area / Overall Document Size
To determine the final bleed size of your page use the following equation:
Final Width = Width of book + 0.125" (3 mm) bleed on trim side. No additional bleed is added to the bind edge. Final Height = Height of book + 0.125" (3 mm) bleed on top + 0.125" (3 mm) bleed on bottom.
For example a 6x9" (229x152mm) book will have a final interior size of 6.125" (156 mm) wide x 9.25" (235 mm) tall.
If using a background color or image please take those elements to the edge of the bleed area.
Pink (Safety) Area
A 0.5" (13 mm) margin is recommended inside the trim for color book interiors. For perfect bound and hardcover titles this is in addition to the required 0.125" (3 mm) gutter margin. All headers, footers, page numbers, body text and all non-bleed images need to remain in those margins. Any elements outside of the safety areas are at risk of being trimmed.
So that would suggest I need a non-colored area on the inside edge of the pages, so the inside edge of the PDF pages should have a white stripe. Am I reading this correctly? I've got my page setup to have a gutter of 0.125in. This  white stripe makes sense for the crossover spread, but it doesn't make sense for the image sitting only on one page.
(This paperback book is going to be print perfect bound. I was thinking about making this a hardback book, but I'm looking at cost options - another matter altogether.)
Here's what the overall image looks like in ID:
