Acrobat 9.5.5 Pro - odd font won't go away

Question

I began creating a new form and hadn't checked the default font.  After making about 10 fields I used Preview to enter some text.  Not liking the result, I had a look at the font being used.  Something called, "KozMinPr6N-Regular," which is Japanese.  Never heard of it - have never used it.  Not sure how it became a default.  I changed the font for those 10 fields, reset the default to Helvetica and created another 60 or so fields.
The form printed fine in Acrobat Pro, but when I opened it in Reader (11.0.06) and tried to print using the Print Dialog, I received the message that "The document could not be printed."  I clicked OK (the only option) and a new box opened that said "There were no pages selected to print."  This after I "Selected All" in the print dialog and saw the preview of the document as a thumbnail.
At one point I was instructed to go to the Adobe website to download a font since "the author hadn't included it."  Well, I was the author and apparently it was referring to this Japanese font.
Back to Acrobat, and opening Document Properties > Fonts I see that Japanese font is included, as well as Helvetica.  Yet I've checked ALL of the field properties and there's ONLY Helvetica in use.  Short of starting all over from scratch, how can I fix this?
Also, I looked up Embedding Fonts in the Help dialog, but that's of NO help since it doesn't tell me how to do so - only the pros and cons.
I'm running OS X 10.9.2.
Thoughts?  Thank you!

I see, I misread your reference to Reader 11 to mean you were using Acrobat 11, but it looks like it worked out anyway.
The base-14 fonts are special in PDF because they are guaranteed to be available even if they are not embedded. If you select a non-base-14 font for use with a form field, the entire font usually gets embedded, since each glyph it contains has to be available for use with the field. This can take up a lot of space if you do this a lot, and the space isn't reduced if you change back to a base-14 font later because the internal reference to it is not removed. This is caused by the bug I mentioned.
In your case, however, the entire font doesn't get embedded because fonts like it (e.g., large asian fonts with a lot of glyphs, Arial Unicode) would take up too much space if fully embedded. If it did, a 100KB PDF could bloat to 20MB with that one change. Instead, users are expected to have such fonts installed on their system, which is why you were prompted to install the font pack. This despite the fact that the font was not actually used by anything in your document, it was simply the orphaned reference to it that triggered this. This should get fixed in Acrobat eventually so this type of thing doesn't happen again.
