Rigidbody causes foot sliding with MecanimBridge

Hi, I have a test scene with absolutely basic defaults, using a Recast graph + RichAI + MecanimBridge for root motion animation. For some reason there is foot sliding when the agent has an absolutely basic kinematic rigidbody attached to it. Funniest part is that when going frame-by-frame in the editor, the issue is also gone. Any tips on what could be causing this?
