Default Help! Where is the URF for volume fraction?

I am solving a free surface flow problem using VOF. I set the Under Relaxation Factor for volume fraction as 1, and it gave very good results. But before I saved any resuts, my computer was down because of power accident.

I tried to recover the computation, but this time, I couldn't find the option of URF for volume fraction. I tried many many times, changing different solver setting and boundary conditions. What's wrong with the Fluent? Where can I find URF for volume fraction?

Please, help!!
