Yeah, that sounds odd.
Especially odd if they files are viewable through Finder. They use the same library.
I hate to say it, but have you tried rebooting? I wish I new which service to restart, but something in the background may have crashed or locked up a file.
Sorry, I'm not more helpful.
If you find a resolution... Do keep us informed. I'm sure you won't be the last person with such an issue.
