Attic Vent and windows disappear

[billemery]

I've had this problem on gable ends with the attic wall duplicated or out of alignment with the wall below.

It seems like that if I place the window or attic vent in the elevation view....It will rebuild without the window. If I place the window in floor plan view by going to the attic floor, I do not encounter the problem...at least not yet.
