Swap Set & Cycle Layers
I have a character who's default arm is behind her.

I have another arm that is outstretched and also a 1-image, 2-frame, layer cycle added (a blurred arm in between).

I've made the arm group into a Swap Set:

I've added the cycle layer behavior to the arm set:

So, my problem is that the trigger (swap set) works, but the cycle layer doesn't.
I don't get my 2 frame blurred in between arm.
How did I set this up incorrectly?
Thanks in advance,
