Select the wall and then choose another profile from the list in the info box or wall settings dialogue.
Are you saying that this does not work for you?
Is the list greyed out?
What happens when you choose another name in the list (assuming you can select from the list)?
Does it make a difference if you select the wall in 2D or 3D?
It can't be that your wall or layer is locked because you wouldn't be able to change it to a standard wall either.
