Why are the critical values for some petroleum components missing in PROII?

I created a hydrodesulfurization model using PROII, where the virtual components of petroleum were entered using distillation curves. As a result, in the \"component properties\" section, the \"Critical Properties\" data for the two heaviest components, NBP520 and NBP582, are missing; however, the model converged. I tried entering the values manually, but when I opened it again after clicking OK, it was still missing. Why is this the case? Is the result of this calculation correct? How should it be changed? Thank you!
