Dwarven Forge pieces don't line up - cavern Double Door 2x4

The Dwarven Forge cavern Double Door 2x4 piece has pinholes in the top and base from the physical version that are unnecessary in AR. The Arch Topper that's meant to go overtop the Double Door has difficulty snapping to where it's supposed to be. Also the Arch topper is classified as a wall, where it should either go under door or prop.
