Help! Qualifier on Resolve 12

This is probably a silly question, but when I'm making a selection in qualifier I cannot see my selection when I put the dropper on the image. I can see on the little node that it is being selected but I can't see it on the image. The old button that I used to press to see it is now gone. How do i see my selections???

SORRY Im RELE DUMB!!! for anyone else who has this problem, above your video there is a "..." , click show view options and the button appears at the top of your video preview. thanks !!!!
