Retain First Layer in Cycle Layers at start and end

Hi there,

I'm seeking assistance on maintaining the initial straight position of the arm throughout the entire cycle in Adobe Character Animator. While I initially attempted to use a swap set, I encountered numerous issues, prompting me to switch to a cycle layers approach with a trigger button. Despite this change, I'm still facing difficulty retaining the first layer at both the start and end of the cycle. Any insights or solutions would be greatly appreciated.

Thank you!
