The head of the puppet does not reappear after a cycle layer

Hello
I added to the head of my puppet a Layers cycle with a trigger to activate it.
When I activate this animation, the head of the puppet disappears and the animation runs smoothly but once the head of the puppet does not come back, I have to press the trigger button a second time to make it reappear. All the Layers cycle added to the head make the same mistake, but the Layers cycle added to the arms work very well
