IKFK Switch Issue - Waitress Rig
 

I've attached an image of the issue I'm having.
I'm still new to maya, but from what I've learned it seems to be an issue with the ikfk switch.
I want to animate in fk.
I've tried switching between the two but the issue is still there everytime I try to key anything

It's for a University Project so any advice or solutions asap pls ;-;
