Can't modify text on Type Overlay in Acrobat Pro 9.0

Question

I'm trying to modify a menu for a local restaurant. They gave me the file as a .pdf file, and it's listed as a Type Overlay file. Advanced editing and touch up text tool do not work (I'm trying to delete an item that is no longer served).
The entire menu page comes up as an object / picture, not as text. Using the touch up text tool does delete the desired text, but it changes the entire layout of the page, moving text over several columns and covering existing text. Trying to realign the text by putting space in the missing pieces location just compounds the problem in several bizarre ways.
How do I determine what type of format this is. It says there are no layers, it appears to be one image, but deleting or changing any portion of the image causes undesired movement of text. How do I delete, or insert text as the menu changes?
Thanks!

Here's an update to the problem I was having.
I couldn't find any way to edit the pdf "as is" in Acrobat, but through obstinance and trying everything at my disposal that had even a slim chance of working, I came up with a solution.
By opening the pdf up in Adobe Illustrator, it gave me the ability to cut / paste, delete and modify the text without problems or errors. I was then able to resave as a pdf. The file works great, and though I still can't modify it in Acrobat, Illustrator works fine until I get the original file.
On a related note, Illustrator allowed me to remove the menu background from the pdf file and save it (the text only) as another pdf, getting rid of clutter but maintaining alignment so it still prints on the menu paper and stays in line with the graphics.
I hope this helps others!
