I have a thermatru french patio door.  The passive door has a handle that operates the latches above and below.  The post above projects 3/4 inch.  The post on the bottom only projects 1/4 inch which isn’t enough to secure the door.  There are no instructions in the installation manual on adjusting this.  I went to their website without luck.  I’ve already tried my installer who can’t figure out what to do because no instructions.  I’m willing to fix it myself if I knew how.  Does anyone know how to adjust this?  thanks
