[FM16] Editor says there are failed changes, but a search reveals none

I have a weird problem: the editor is telling me that my file has 46 failed changes but there are no failed changes when I do a search for them. The problem stems from some sort of issue with stadiums I've created from scratch and only pops up when I try to change the information (i.e., change the stadium name or the city). So, editing the stadium information causes the fails to appear, as does deleting the stadium(s) and creating new stadium(s). I wouldn't care if I was locked into using the existing number of stadiums (there are enough for my needs) but I don't know why the errors are appearing or where the errors are taking place.

If anyone has any insight, it would be appreciated.

Thanks!
