Longtime user and running

Hello All -

Longtime user and running in to a strange situation. I recently installed two Leviton DZ15S switches. They’re working fine as expected but they associated with a Category and SubCategory of “3” which appears to be some sort of appliance module.

I’m trying to switch to a Category 3 and SubCat 1 (Light) but it keeps reverting after a reload.

What am I missing?
