"Saving MetaData" On individual pieces of audio stuck at 66%

In my current project, several pieces of audio have been stuck at 66% in saving, which started automatically after I recorded them. The time keeps counting up, and I can't save the whole project itself (it gets stuck at 0%, I assume because the other clips are still saving). Any help is appreciated, this is for a homework assignment and I hope I can get an extension on the deadline!
