wall color default

[lilaansell]

I am using HD Suite 7.0. I have chosen the default style and then created all my own defaults and saved it. For interior wall color I have chosen "butter", for exterior "red". I have 2 problems:
1. When I create a new exterior or interior wall, the color reverts to the original defaults supplied with the software (bare sheetrock, and gray), so I have to select the wall and change it. Am I missing something?
2. After I change the wall color, if I have a lofted ceiling, the wall triangle above 8 feet is still bare sheetrock. I don't know what it's called or how to change it. I have gone through all the defaults and can't even find the sheetrock it's referring to. I have tried deleting the roof, changing the wall color, and rebuilding the roof. Any ideas?
thanks, LIla
