"Rapid Rig: Modular" - Procedural Auto Rig 2.4.8 for Maya (maya script)

The CTRL worked properly when Follow is on main ,but when i used the other follow option that have a lot of problem ex: if i scroll the time slider back and forth, the pole vetor position changed.  When i put a new key i have to re ajust the last key position, so if i dont use the main follow some time i have to put a key on each frame to fixe the pole vector position . Note I'm not animate using the MAINC ctrl, my character is far a way ftom this ctrl, i dont know that's have any importance. Also i can send you my file if you want.
