Bug in audio waveform display / positioning in Cubasis LE 2

Version 2.8.1
Ipad Pro 11" (2018)
iOS 12.4

When I import long audio files (more then 8 minutes (mp3) the zoom works correctly only to certain level, then waveform starts to jump around the screen and also changes position vs timeline. See the video: https://youtu.be/WhIrunKUgFE

There is also some kind of snapping to invisible grid (while snapping magnet is set to OFF) that prevents user from moving long audio to align with bar precisely.
