Does this happen without Optifine / on 1.16.5 too?

Removing Optifine fixed this, didnt even think about it to cause issues like this :/ Now to find another mod with optifine like zoom function, really liked it and only reason I love that mod :/ Thanks for help though and fast reply!

OptiFine has a reputation of causing rendering issues with mods. It's odd it's happening on those models since they're just normal Minecraft block models, but yeah this isn't something that can or should be fixed here.
