Losing my mind over Substrate decals

Hello. So I’ve been trying to create decals with the new material system and it just doesn’t work. I’m doing everything that I’m supposed to do afaik. But when I drag the material onto the scene, it still acts as a regular material, not a decal. To make things worse, sometimes it works, but then when I redo the material, it suddenly won’t work. Meaning that, I did the setup from the screenshot and it worked, then I recorded a tutorial and suddenly it didn’t work again. Here’s the setup.

Is there a particular setting I’m forgetting about?

EDIT: I can confirm this is a bug. Unplugging and replugging the purple pins fixes the issue.
