Reply to loop recorder starts on play start

Ran into a strange issue recently with TSP2 and my S4, where after I open traktor, load a track into any deck and hit play, the loop recorder automatically starts recording. I've looked through my settings menu (albeit briefly, and I'm at work now so I can't check it immediately) but I didn't find anything that would indicate a loop recorder auto-start or anything.

Anyone have any ideas how to turn this behavior off? I've already tried deleting all mappings and then re-adding the default S4 mapping to no avail.
