Character rigging and animation check

Hi, I’m new to the forums, so forgive me if this has been asked before or if it’s not the right place to ask.

I recently submitted a rigged character to the marketplace and got back a failed review, it seems that my character wasn’t deforming properly to the animations they tested with. Does anyone know which animations they use when testing?

I tested on my end with the Animation Starter Pack animations and the Third Person project animations but I haven’t run into the issue they’ve marked in the review, so I’m having trouble duplicating and addressing the issue. Here’s the exact feedback from that portion of the review if that helps.

If anyone has any insight it would be greatly appreciated.
