MuseScore 4 misses off bars in Part scores

I have noticed that when creating parts in MuseScore 4 for a file, it cuts off dynamics towards the end (e.g. a hairpin) and a whole bar is missing, as well as a tempo instruction that was applied while all 3 instruments were selected. Also, in the harp part, a random line appears in one of the last bars.

Also, I have noticed when editing that last bar, it will only allow me to place notes into it if it is NOT a certain bar number. So basically I had to add extra bars before this last bar, in order to edit it. If the last bar was bar number 28 if I attempted to add notes, the program crashes and quits instantly.

I am using macOS Monterey 13.0
