Multiple masks on one layer not working

[phoenixrider]

I am on Premiere Pro CC 2017

I used to do this a while back on older Premier Pro, but I have one layer with mask 1, mask 2 and mask 3. invert one, is fine. invert another all maskes off. I have read set the mode next to invert but I believe that is AE only as there is none in PP. Is there a way to see the bottom layer with 3 masks on the top layer?
