Icon Models Invisible In-Game

[Teld]

Hey I'm trying to make a custom hero select UI using the Button.mdl and replaceable textures, but when I load the game, all of the models are invisible. I can see their shadows, but the button icons are gone. I can see the proper icons just fine in editor though, I have no idea why this is. What's more, is that on another map, using the exact same process, the icons are visible, it's only in this new map that I can't see them.
