Why are Primitives still showing up?

Did you ever publish them previously? If yes, and you only recently checked that hide from publishing box, you will need to push out a new update to “hide” them.

Are you in the same library file that they are defined in? Hiding them from publishing won’t prevent them from showing in that file.

I have published previously I’ve always checked “hide” for a while now and there have been numerous published since then. Still shows up.
 

I am in the same file it’s defined in, but it shows up in other files when the design system is added.
