FK/IK arms detaching from result joints


I’ve run into a strange issue with my fk and ik arm not rotating or translating properly with the result arm. Everything is oriented correctly and the fk/ik switch functions as it should, the arm works fine until keyframes are added then it comes apart. This is only with the left arm, the right arm works fine which is a little odd considering the left arm was built first and the right arm is the copy.
