CST： parameters S 12， S 21 and S 22， do not work.

Hello everyone, I have problem with CST, it does not demonstrate the parameters S 12, S 21 and S 22 in the graph. Strange that the s11 parameter appears normally.I would like some guidance from someone, why this is not working please.

Did you simulate a 1-port circuit? What S-parameters would you expect then?

sorry I did not pay attention to it, true if I'm using a port not the other parameters
