3 pane sliding patio door lock

From what I can see in your photos, it seems your parts a little worn. I believe our 82-056 Andersen lock and 82-048 Andersen latch could fix those issues. Also I notice it appears you may be missing the bracket. Look over our 82-057 bracket for the operating door and 82-058 bracket for the stationary door. These may be the parts you have been searching for. 

 All of the hardware you have on your door seems correct, but I can't really speak as to whether they're installed correctly. I'm not sure I'm understanding your problem, though. In what way is the handle preventing the door from closing?

I can tell you that your current handles are newer versions of the old handles that used to be installed. Those two holes on the exterior frame you see are where the old handle used to go. That said, the new handle should work just as well. Andersen designed it specifically to replace the old version.

I once brought this up with an Anderson repairman. At the time he told me it could be used as a replacement, but never told me how. Would it be possible to drill new holes to set the handle just below or above the existing holes? That way you can make the set back that you need.
