UE 5.8.2 Modular Rig Foot starching problem

A simple Base Mesh i have rigged using Auto Rig pro in blender and export via ARP (Auto Rig Pro)'s FBX export Window. After Importing In UE5.8 everything is working fine include Retargeting Fab Animations. Now After I add Control Rig in the sequencer the problem begins.

problem 1) Until i make Control Rig Layered only then i can tweak my animation. Otherwise it’s standing still.

problem 2) Both Foot starching and IK Pole hide inside the knee.

Please can anyone help me.
