Score display kept changing when entering the notes

We are using MuseScore 2.0.3, and win 10 system. Currently we found one thing really annoying us is that after we change a key signature in measure 184, the score display kept changing with following note entering. Even though, the score has not been changed, but it really adds some inconvenience in score editing, since it's hard to locate the notes. Would you please fix this?

Attached is the score and 2 samples of the problems.

Thanks,
Sherry
