Can't Change Time Signatures

I'm trying to change a time signature in my score, but every time I hit delete on it, MuseScore keeps crashing. This has also happened on a different score I've made (that no longer exists), but the problem still stands.

Simple way to reproduce the issue:
1) Add a time signature
2) Create a time signature change
3) Try to delete the new time signature
4) MuseScore will (probably) crash
