Mixamo Humanoid Rigging problem

Hello
I've been using Mixamo to rig my humanoid characters for a while now. However recently they come in messed up usually the shoulders are squashed in.
The export from Mixamon is .FBX for Unity
in Unity the model is successfully set to Humanoid and I enforce T-Pose...

It looks fin in Mixamo / it looks fine in .fbx player, but Unity squashed the model - it is cutting off the left breast of each of these girls...
I really appreciate any help
