Question How to change molecular weight of a species in pdf-mixture

I try to solve a reaction problem using non-premixed combustion with steady flamelet model in FLUENT. However, FLUENT gives the wrong molecular weight of one species in the flamelet-mixture.

After I change the molecular weight in the material panel, I generate PDF table and again FLUENT gave the wrong molecular weight for this particular species. This time after I change the weight in the material panel, save it and run for a few iterations, FLUENT change the molecular weight back to the wrong value.

If anyone knows how to change the molecular weight of a species in the PDF-mixture permanently, could you kindly tell me, please?
Thank you very much,
