Falls disappear when creating parts and transposition instruments.

Hi, new to musescore here! I would really appreciate if there are some workarounds for the following problems I encountered:

• While creating parts the "fall" symbol (in arpeggio and glissandi) does not appear in the parts and have to be placed again in the score in order for it to appear. If I save and close the project it disappear again from the parts (score remains ok).

• Changes to measure number position in the score and individual parts (Format - > Style -> Measure Numbers) resets after reopening the project.

• This is a weird one: I had a Tenor Sax Part and tried to add the Alto Sax Part in order to have all the saxes in the same part. While doing so the Alto Sax appeared with the wrong key BUT the notes were in the correct line/space as if the key was correct. Same happens if I create this new part from scratch making visible the instruments I need. Had to set again the key signature in order to fix it which is very annoying.

• Finally written tempo does not follow playback tempo. Is there a fast way to solve that instead of adjusting the % of playback speed?

Thanks!
