Issues with Chaos Strike and GSE

Any other Havoc enjoyers having problems where the rotation hangs up and does not use Chaos Strike? I’m just coming back to WoW and GSE after a few years hiatus and am wondering if anyone else has ran into this issue. if I do a /reload in combat it fixes the issue for a bit but chaos strike could hang up on the next pull.

Is this something to do with the ability becoming Annihilation when in Meta form? or am I just screwing up something on my end with GSE

Thanks in advance you lovely people
