After I adjust mesh and exit it disappears

I’m trying to learn how to use the mesh tracking in Mocha Pro. I’ve watch a few videos and I’m trying to use it the place blood on a face. I get a decent track but not perfect. As he rotates his head the blood slips on the rightside. I went back in and adjusted the mesh manually. When I exit Mocha Pro and return to the plugin in AE the track is gone and I cannot figure out what I did wrong or how to fix it.

Does that makes sense? I lack the vocabulary to to get this out.

I unchecked “Apply Matte” and see that my blood has moved significantly off his face but the matte is exactly where it should be.

Obviously I did something wrong. But what?

I’d really need to see this to diagnose the issue. Can you send me the shot and ae file? MaryP at borisfx.com
