Unchaning surface temperatures despite change in Phase Change temperatures

Basically I'm wondering why the values for indoor and outdoor surface temperature aren't changing for this idf file when they should change as accompanied by the change in the enthalpy-temperature curve as described in MaterialProperty:PhaseChange.

I've tested it on the 'CondFD1ZonePurchAirAutoSizeWithPCM.idf' example file and it seems that there weren't any problems with the example file. I'm sure I have the required classes when I compared it against the example file.

For example when I change PCtemp 2 from 20 to 30 and PCtemp3 from 20.1 to 30.1, all the values for the surface temperatures remain the same, they should change but I have no idea why they don't. The example file shows a big difference, this one doesn't and I have no idea why...
