It's not telling you to kiss her (Kisu ŝin = "Kiss her") but saying that you do kiss her or you are kissing her. It's present tense. It's describing a situation which, I guess in your situation, is not true.
I don't know if the questions appear always in the same order, but in my case DuoLingo has told me that she loves him and me, then she kisses him and now you kiss her. This is getting more and more dramatic.
