"Pitch Change" changes all tracks instead of just the selected

I tried searching for someone with this problem but found nothing

I tried in just 2 tracks to see the problem and goes like this:

  • Select “track 1”(just track 1) and change the pitch to “6”
  • Then select “track 2”(just track 2) and the pitch is already “6”
  • I then change “track 2” pitch to “2”
  • Go back to “track 1” to see the pitch and its now “2”

Why is the pitch changing for all of the tracks? i tried and searched everything and even deleted and installed again, does someone knows what is this and how to fix it?
