Cursor activates random turntable controls while typing song search...

After updating to MacOS Sierra, I am experiencing an issue where the cursor will jump to the “loop” or “set” button while trying to type a song title in the search window. If I type slow and deliberately I can avoid the problem, but typing slow is not a luxury during the throes of performance.

This has happened a few times before on a very seldom basis, however the frequency of occurrence at tonights gig was near disabling. Could it be an issue with the new OS?
