BEopt v2.8, Problems adding ceiling and roof insulation

edit

For an unknown reason, I cant seem to add options that include both ceiling and roof insulation. I have tried with all of the versions we have on-hand (2.3, 2.6, 2.7, and 2.8), and none of them seem to be able to do it. I can add them to the Options Manager library, but not the energy models (even when I toggle "In Current Project"). Running in single-family mode with E+ as the backend.

Any help would be greatly appreciated!
