Capsule Collision shape alignment in Mesh Editor not matching actual Simulation

(UE 5.5.3, 5.5.4)
Whenever I apply a Capsule collision to my mesh, when I run the Simulation the alignment is off by 90-degrees (see screenshots). All the other shapes work fine. WTF is going on???
I also did a complete uninstall / re-install of UE - same issue.
