To resolve the issue in your example use 10.66 for your "Target PG" value.
The problem you are experiencing is one of the reasons that this calculator was created: http://www.e-cigarette-forum.com/forum/diy-e-liquid/424235-new-calculator-try.html
Do a "File->Save" on your example recipe. Install the calculator at the link above and after launching the new calculator import the recipe you saved (Tools->Import from eJucieMeUp).
10.66 shouldn't work either. He's using 11 percent of non vg items in the example. The highest percent of vg he can have is 89 percent, and the lowest he can have is 33.33 percent (because his nic is vg). Hope this helps.
