Pole vector rotating foot joints that are parented to foot constraint


Hello, I am trying to rig a quadruped character and I have still same problem with mirrored legs. I am working with tutorial, link below and this is still happening:

On original leg I used Limb 3 and 5 rig from tutorial and everything works perfectly, but on mirrored leg, when I move pole vector used for knee, it starts rotating even joints on paw with IK handles parented to controler. Did anyone had the same problem?

For better explanation I upload video which show my problem

Thank you guys!
