Clip jumps in musical mode

I recorded an short audio clip starting from position 0.0.
When I enable “musical mode” (the note in orange in lower part), the clip jumps c.200 bars (red circle). And each successive click in “musical mode” push the clip c.200 bars forward.
What is happening? What I am doing wrong?
Any help is really appreciated.

The orange note is not “musical mode” it is “musical timebase”

OK, thanks! I found the “Musical Mode” in “Info Line” and it does not cause the clip jump.
I dont understand however why the “musical timebase” causes that?
