Google Docs Repository doesn't show all files

I'm trying to setup Google Docs access on my site.

I'm able to login through the filepicker and see my Google Docs but not all files are showing up. Right now all I can see are pdf's.

When uploading files to Google you are given the option to convert. If I don't convert all I see are pdf's. If I do use Google's convert I can then see Microsoft Word Docs as well as pdf's. Other files it takes and appends .rtf to the end. I don't see this in Google and only assume this is done by the filepicker.

Is this a bug or is this supposed to be how it works. None of the documentation I have seen says what it should and should not show.
