Cloth Constraints not show

Hi,
I have added a fabric component to my object and I want to change the constraints.


But when you click on the “Edit Cloth Constraints” button, nothing appears on the model for editing.


I’m using Unity 2019.4.7f1

Switch Gizmos.

Switching the Layout to Default usually fixes this, and other “window” related bugs. I switch back to my prefered layout after and it’s still fixed.
