Cast on Critical Strike (CoC) forcing weapon swap and failing to activate on secondary set

I have Cast on Critical Strike (CoC) set up on both Weapon Set 1 and Weapon Set 2. However, when I use a skill (e.g., Arc) assigned specifically to Weapon Set 1, the character automatically swaps to Weapon Set 2. Additionally, even though 100 Spirit is allocated for both sets, CoC fails to activate/trigger while holding Weapon Set 2.

same problem idk how to solve it
