Deco graphics for plate helm are incorrect

Here's what the lootable plate helm looks like when worn:



He's what it looks like as a deco object (see the table, just by the candelabra):



In the former it's a full helm, in the deco version it's only a cap. Actually I'm guessing that the graphics are same/similar, but the registration point on the supporting surface is too low, so only part of it is showing.

It's same in every blacksmith and armor shop out there, including the abandoned ones in Tenebris Harbor. Also in some adventure scens, such as Hilt Fortress.
