I fixed this problem by copying my contacts to my phone (not the sim) and making sure the ringtones I wanted to use were in the correct folders (I got them from Zedge; the storage area isn't the Contacts default). If you are still having this problem, try it.

EDIT: When you do this, turn off Ringtone ID entirely.
