Inordinate head loss across a general-purpose valve

I have a WaterCAD Connect Edition Update 4 (10.04.00.108 64-bit) WaterCAD Model NEW.wtgmodel prepared by one of my staff in which we are getting some very strange amounts of head loss across a GPV used to model a water meter.  Based on the flows for the demands of the development, we should have a very minimal head loss across the GPV. We have put in a GPV and a curve for the meter per the manufacturer data sheet.  I am also getting this strange head loss through the GPV used to model the back flow preventer. 

The flow through the meter is 9 gpm so the head loss should be about 0.1044 feet.  When the model is run, I get a head loss of about 47 ft through the meter resulting in an inordinate amount of pressure loss.  The same thing happens for the back flow preventer modeled as a GPV as well but with different head loss about resulting with a -220 feet hydraulic grade after the BFP.  

I have compared the properties of the GPV of another project that I prepared and I cannot spot any issues with the data.  I have checked the elevations, pipe sizes, head loss curves, etc.

Removing the meter and back flow preventer or putting in a zero head loss curve, the model results appear normal. It is clearly something to do with the GPV and the curves.

We are modeling this with the GPVs as the municipality requires different flows for the domestic demand model and fire flow runs.

Any ideas of what I am missing here would be greatly appreciated.
