I believe that that CI wall coverings uses the standard Graphisoft accessory plug-in, which does not recognize CP walls.
At least with the standard GS accessories, the add-on was written before CP walls were introduced and has never been updated - thus only working with conventional or composite walls.
CI support is really good, typically responding within a day, so you might want to ask them directly.
