Un highlight area

Probably stupid question, I am having trouble un highlighting my track, and now whenever I click somewhere on the track to highlight a different section it just automatically plays ? Its like I can’t take the dark grey highlight off of it…frustrating me to death lol…happened when I clicked ctrl a or cmd a

Ensure that you click on the actual waveform, not on the “ruler” (the “Timeline”) that is above the audio tracks.
Clicking on the Timeline is a “quick-play” feature that allows you to quickly play any part of the project.
