MPC 3.4.3 BUG REPORTS

When working in the Arrangement view and trying to copy paste notes, I get very inconsistent behaviour. The pasted notes always jumps way off and I need to nudge and transpose them to the intended location.

Perhaps user error. But I'm not finding a way to select the notes, copy them, and then place the timeline cursor where I want the pasting to happen. Anyone able to have precise control over where to paste notes? How do you do it in that case?

With the Mpc slaved and following program changes from Octatrack. The MPC jumps to a random sequence when pressing double stop quickly on my Octatrack.
