Playing the wrong title

Hi, I am experiencing a really strange bug:

Sometimes when I press play the counting starts and after that the showed lead sheet jumps back to another lead sheet i played recently and plays that one. What is exactly happening is hard to say because I had this bug round about 10 times in the last days.

My configuration is: The newest iPad Air, iOS 14.2 and iRealPro in split view.

Apropos split view: When iReal Pro restarts in this view, the last position is not remembered, right?

Had it again and this time time the lead sheet changed but the top line (with the original title) stayed the same. Then I pressed pause, the wrong sheet is still shown, but after pressing stop the original sheet is redisplayed. Wow....
