Trackpad stuck in right click only mode

Describe the bug
Every once in a while, (maybe after an accidental series of keypresses,) my trackpad gets stuck in only right-clicking. When I normal, one-finger click, it always pulls up the two-finger click menu, and I can't left-click! (ctrl-click doesn't work.) It also seems to interrupt some keyboard shortcuts. The only way to make this stop is quitting/restarting BTT. It's entirely possible that I am just hitting some strange key combination and engaging some unwanted feature, in which case I am sorry to post here! I just can't seem to figure it out. Thanks!

Affected input device: Apple Trackpad (Internal and External), Keyboard
