Maybe the TBO Facebook sees one or more of those and finds they don't quite match up. Might have to find those files and manually move them out. Then, after a dalvik wipe maybe, try to install the TBO Facebook again.
Not really sure though. I haven't used Facebook proper in a long time. Since I'm a light user of FB I make do with apps like Metal instead.
