Limbs get disconnected from the body with walk behavior

[Palermo5E62]

Hello everyone!
I recently started using CC and I've been enjoying it a lot!
However, I've been having this problem that when I add the walk behavior, It seems like the limbs get disconnected from the body.

Does anyone have any idea how to improve this? I check the layers in .ai file and watch several tutorials, nothing really help. I don't know what to do!

I appreciate any tip!

Hi I hope the reply is not too late. The reason libms disconnect during the walking cycle is that you did not tag the waist and the neck. I think the waist is the most important for the walking cycle.
