This is odd. Before seeing your last post I renamed my XML file, restarted Recipe Calculator, and VG is listed as 50% in Ingredient Editor.
Next, new install: I uninstalled, re-downloaded, and installed the program. Removed the XML file and it's folder. After starting the program and going directly to Ingredient Editor, VG is STILL listed as 50%. ??? Where's the program getting the "50%"? Maybe the registry?

The value listed in the add/update ingredient screen is indeed 100%, with "VG" as the type, so I guess calculations will be OK.
