In the HUD layout, keep in mind you're setting where the top edge goes, and item descriptions can be different lengths. Set it high enough that even the longer descriptions will fit.

In fixed reversed, it will still use the HUD Layout position to determine the height of the box and how close to the edge it is. It only switches which edge it will be that close to.
