Weighted Overlay Problem - "Restricted" not working.

I’m having trouble with the Weighted Overlay Analysis.  I have three raster inputs each with values of 3, 2, and 1:

 

  1. Affordable Parcels
  2. Large Parcel Patches
  3. Building Presence (only covers Chatham County)

 

The Building Presence raster has pixels with no data value that covers pixels from the other input rasters.

 

Therefore, if I set this value to “Restricted” in the analysis window it shouldn’t be considered in the output…

…except that it is anyway. The areas of No Data in Building Presence are overwriting the other rasters.  I’m at a stand-still—this is perhaps a nasty ESRI bug.

 

I have attached a geodatabase with the input rasters and four Weighted Overlay attempts, showing how the area to the southwest shows no values.  Please help!
