Is there a way to prevent slurs from reshaping after closing and reopening?

I've been using MuseScore for a while, and recently after closing, a few slurs will take shapes that I hadn't left them in before saving. It happens most often with slurs across systems (the attached image) but it also happens with slurs from grace notes.

If anyone knows either the reason or the solution, I'd love to hear it. Thanks in advance.
