New Masking Tool Not Capturing more than 1 frame, then it disappears during tracking

I am having issues with the new masking tool. The tool quickly finds my subject, and then adds it to the Unassigned Masks section; however, when I click forward and back to track the motion, the outline disappears as it goes through the entire process. After it's done, if I scrub through the clip, the mask outline appears only on the frame I chose the mask. I have tried multiple clips and projects with no luck. Any suggestions? (ohhh and if I stay on the one frame that has the mask outlined and move it to a effect it works, but then stops working after stepping off of that frame.
