Sequencer control rig updating problem

does anyone had problems with control rig layer in sequencer, i have a retarget animation for my metahuman and the layerd control rig sometimes doesnt update so only the retargeted animation plays and the keys on the control rig gets ignored. I should mention that in the sequencer the control rig sometimes moves with the character and sometimes not. But in the master sequencer the keys i set are never build in. i could find out how to solve it. some guy said it has to deal with the backward solve but the metahuman it self has a pretty complex backward solve build into its control rig so in my mind that couldnt be the problem.
