Problems with recorded audio

Hey everyone,

For about a month I’ve been running into a problem that is just driving me crazy by now.
When I am recording a part of a song it seems fine (timing-wise) when I look at it, but right after I stop recording the recorded part seems to snap into a different position leaving me with always missing the 1st note. I’ve tried a lot of things but nothing seems to make a difference.
So far I’ve spend about 20 hours reading forums etc and trying out different things but the problem still persists.

Here is a screenshot showing the problem

If anybody could help me out, that would be really great, thanks in advance.


Could you make a video screen recording, please? How does it look like while recording and how does it jump after, please?
