FK/IK Switch fingers not following either kinematics

[nassirhazim266NJ]

I tried making an FK and IK switch for the left arm and the left leg, but I can't seem to figure out how to have the finger joints or feet joints follow the skeleton with both kinematics. If I delete my finger controls, it does follow, but I want to know how I can keep my controls and have them follow for both IK and FK.

There doesn't seem to be an arm IK in place in the file you attached. There are constraints present from perhaps a previous IK? To move forward, I'd remove the left over constraints and perhaps look at video tutorial such as this one (audio is a bit noisy but the content is correct) https://www.youtube.com/watch?v=8HX7Np8eeo8
