@Anonymous You are looking at an elevation view in the family. Type VG. This will bring up a dialog box. Go to the Annotations tab - you will see that dimensions and reference planes have been turned off. Turn them back on.
Go to the top Floor Plan view. When you click on the middle reference planes, you will see their properties in the palette. Right at the bottom of the palette - click to check Define Origin. You want to change this for the vertical as well as the middle reference planes. Click Load into Project.
In the Project - ungroup; the reference planes - since they were arrayed, they have been grouped. Drop in the windows. You will need to Align each window twice (don't ask me why) but the windows will move to the reference planes. Basically, the windows will align to the point where the reference planes intersect the Origin (which you have just fixed) of the family.
Take a look at the attached fixed file, and reverse engineer to see what I am talking about. Good luck!
