There's definitely lots of things I've done that could have caused it - I'm not thinking the rim/firmware is to blame. I jist wondered if anyone might have insight as to what to look into. It pretty much shows up the same on any app, and in terminal 'ls' for both /media/sdcard and /run/media/nemo. The strange thing is that all of those partitions are actually mounted there. If I umount, for example, then the entries go away, but then those partitions are inaccessible. I probably messed up something while messing around with mount command...
