Error 1100: One or more phases associated with reaction R1 has specified constant specific heat (C_PG0/Cps0). This is not permitted for reacting phases

I want to make a simulation about plastic melting, but I met a mistake. It said:“One or more phases associated with reaction R1 has specified constant specific heat (C_PG0/Cps0). This is not permitted for reacting phases.” but I feel that the specific heat capacity of my reactants and products is not constant, could you help me, thank you very much.
The reactants, the products, and the equations are what I’m assuming, because I don’t have the actual data from the experiment. This is my zip file.

The solids phase “sulio” is set with a constant specific heat. You need to change this to “mixture”.

Wow, thank you ao much!
