Minecraft v1.21.1
Domum v1.0.204

I have a bunch of mods, so maybe it's due to that, but all materials I've tested so far are vanilla. The textures remain consistent with the different combinations, they're just pulling the wrong ones. It's either wrong in the inventory or when placed. I haven't yet found one that's both.

If there's something the team wants me to try then let me know. If not I'll just rollback versions and wait for an update.
