By any chance are the walls the windows are sitting in placed in an emtpy opening within another main exterior wall?
IF yes, then in the settings for the empty door/window set the
'Connection on the Right' and 'Connection on the Left' to OFF.
IF this isn't it. can you give us some more info including screenshots of settings?
