SubD inside block doesn't reflect - possible bug?

Hi

I’ve noticed some strange behavior while editing SubD geometry. Sharing just in case that it’s a bug.

SubD “Reflect” not updaing within block. Block was created with alreadz SubD reflextion applied on the geometry. While editing the block, geometry changes not updating on the opposite side of my “y” reflection plane.

Workaround: Run “reflect” command, remove existing reflection plane, apply again the same.
