Confused about sleep vs sleeping for dormir

Question

Hello,

I had this kwiziq question: Catherine ________ à l'hôtel ce soir. (Catherine is sleeping at the hotel tonight.)

I put the answer for the blank as "est en train de dort", but instead the answer is only "dort". I thought that "dort" would = he/she sleeps (not he/she is sleeping)

I thought that dormir = (to) sleep; être en train de dormir = sleeping.

Thanks for the help!
