Is the anyway to check that a "Flat ceilling under this roof" is applied to a specific room?

Running Hevacomp, Design Database for Heat losses. (V8 SS1 SPB (V*i SS1 CP3 (06/16))

I want to apply a flat ceilling to some rooms since they are 3.6m high but have a ceilling at 2.7m.

The problem is when I click the "Flat ceilling under this roof" - See screenshot: test2 (Z:\1600-1699\1685 Shirley Road Medical Centre\Calculations\Hevacomp\GA Plan from PDF.dxf) (gyazo.com)

No ceilling seems to be applied to the rooms, and in the room surfaces it shows only an exposed roof showing - see screenshot: Change room TEST1A - Gyazo

Is there anyway to check if an exposed roof has been applied?

Kind Regards

Toby
