Copy-paste a score with pickup measure in another, after immediate removal of the first one in "Instruments dialog", leads to corruption

Version 2.2.1/ 2.1 / Windows7

1) Default "Untitled" score
2) In staff properties, change the actual duration of the first measure eg to 2/4
3) Enter some notes (but not really necessary)
4) Ctrl + A -> Ctlr +C
5) Press "I" -> Add a score for flute + Remove the first default score -> Ok
6) Ctrl + V on the flute score
7) Save/Close/Reload

Result: corruption

• This doesn't occur by removing the first score not in step #5, but after step #6 (and returning in "I")
