Dungeons Gear Mod Issue / 1.16.5

How it looks inside inventory: (looks fine even with the mod)

How it looks in F5 mode: (messed up armor texture and gauntlet wrongly placed)

How it should look:

Any idea what makes Dungeons gear mod's armor different from Ice & Fire's armor? I&E Used to have the same issue with armor rendering but recently it got fixed on their side somehow after a few updates. Maybe if you three guys get together I'm sure you'll find a solution.

As for the "pictures below" do you mean Optifine problems ? If so I did restart minecraft many times and didn't work.

Every armor in dungeons gear mod doesn't compatible with my model autogeneration. There's no way to fix them now.
And please relaunch Minecraft when you get a problem like the pictures below.
