Multi track select and Zoom question

When I select all tracks to perform an edit, i.e. for moving the tracks to the left of the edit closer to the tracks on the right of the edit (slice), and then Zoom in or out, the selection does not consistently stay selected.
Sorry, having a tough time figuring out how to describe this. Nevertheless, it’s a real problem for me and I wonder what I’m doing wrong.


Could you please make a video screen recording?
