AutoWear Double Tap not Working?

I have a Zenwatch 2 and I can't seem to get a double-tap to work. I created a simple screen with actions for tap, double-tap, long tap, and swipe. Everything work fine except for the double tap. It simply registers a regular (single) tap.

Any ideas about what might be wrong?

 

Solved my problem. It turns out that if you have "Magnification Gestures" turned on for the watch (found under Accessibility in Settings), it won't allow the double-tap to function. I had turned them on when I first got my watch thinking it would be handy on such a small screen, and had forgotten all about it. But as soon as I disabled them, my double-tap commands started working.
