BUG Probuilder cylinder normals appear to be the wrong way round.

Iv’e got a problem with pro builder in unity 2019.4.3.f
I am trying to make a can of soup asset from a probuilder cylinder, but all the normals on the cylinder appear to be the wrong way round. This has the effect that if you attach a rigid body to the cylinder the cylinder falls through the scenery and the soup can label renders as if it’s inside the can. This doesn’t happen with regular unity cylinders. To replicate simply create a basic probuilder cylinder and don’t do anything to it, attach a rigid body collider and watch it fall through the floor. To cure it mark the mesh as convex in the collider, but this does not stop the label being rendered as if it’s inside the can. It appears the winding direction is the other way around from unity.
