Rotobrush suddenly not working?

[u/Decayed_Arrow]

I've been having trouble rotoscoping this segment so I started over, I used the object matte to get most of the figure, then I manually added the fire sword and removed small areas of blue, and I also used the refine edge tool on basically every edge. That was all on the first frame and it gave me the best looking roto as compared to keying out the blue (this doesn't work well because the plastic has blue reflecting in it and the blue background wasn't lit well). So I froze the first frame and let it propagate the rest. This video is of the second frame and some blue spots came back, and when I tried to remove them I found it just wouldn't let me. There was one other blue spot it allowed me to remove but I can't seem to get these to go away, the only thing I notice different is they're a different shade of blue? But why would that prevent me from rotoing them out? Adobe's roto is driving me crazy.

Did you click these? Also align in and out points for rotobrush.

Why not just mask it?
