A symbol in the Track - how to change/remove it

Windows 10 pro OS build 19041.630 Audacity 2.4.2
See the attached. When the symbol I indicate by the green arrows is on, a cut/move/paste takes in ALL tracks, not just the one you want to edit. I want to turn that off.

That symbol shows the “Sync-Lock” has been enabled. Turn it off in the “Tracks” menu.
