Zebra SubD bug in Rhino 7.2

The Zebra command works well on NURBS, but it does not work well on SubDs. The problem is that the mesh cannot be adjusted. When I click on the Simple Controls button (shown in the following screenshot) the entire mesh window disappears. When I click or change anything else in the mesh window, nothing happens.

Hello - do you find the mesh to be insufficiently accurate for a good read of the zebra?

It is good enough for my work - I do not need perfect surfaces.
