I get a different minimum reflux ratio
I am using the latest version of DWSIM, namely, 6.4.6. I have followed every step exactly, I think. I get the minimum reflux Rmin to be 1.0352 (and not 1.65, as mentioned in the tutorial). As the reflux used is 1.5, which is higher than Rmin, I get the minimum number of stages to be 7.6 and the actual number of stages to be 15.013.Are the above values expected, or am I making any mistake?

Changing the pressure units during the simulation
I am about to enter the pressure as 1 atm. Unfortunately, only bar appears as the available unit for pressure. In the units input page, I did select C5 and pressure unit as atm. It is possible, however, that this section was accepted. Is it possible to tell DWSIM now that it should use atm? In other words, is it possible now to change the units?
