Multiple Material Toggles in Avatars 3.0?

I’m working on a model and I’m having an issue where using more than one material toggle on the same object will only use the first loaded togglable material. I’m trying to have at least two alternate material toggles on one model, and I was wondering if that was possible or if it’s limited to only one material toggle? Or if there was another way to go about setting up more than one, because creating simple toggle animations for both will only allow the first toggle’s material to display in vrchat.

when you preview the material swap in the animation tab after making it properly, does it not swap as it should? if it doesn’t, are the materials that aren’t working on element 2 or 4 of the avatar?
