Icynene attics

What is the proper way to enter the insulation in an encapsulated attic with R20 foam insulation at the roof level, with no ceiling insulation?  I try entering it at the roof tab, but the ceiling page still requires insulation on it, so I put R0 on the ceiling tab.  The house fails worse this way than if I use r30 batts.

You have to add a "1" for insulation at the ceiling plane.
