ImageStacks is not showing up as an option in the SlicerMorph extension

Hello, I have downloaded 3D Slicer 5.10 for macOS and I also installed the SlicerMorph extension. Unfortunately, ImageStacks is not showing up as an option. I have tried reinstallation of both 3D Slicer and SlicerMorph. Does anyone have any idea why it seems to have not be installed?

Thanks!

Cant replicate on my mac. Can you show the full log from you slicer session after you install SlicerMorph and restart slicer (cmd+0)
