Mocha Pro "dilate" effect showing in editor, but not rendering

I need a small dilate over time effect to avoid a jarring transition on the tip of a nose.
It works fine in the editor, but the rendering does not include the dilate effect.

The first two images are what the two transition frames look like in the editor. They show the correct first two images of the transition.
The second two images are what the two transition frames look like in the render. They show a jarring transition where the nose goes from dark to light in one frame.

My render settings are:
Format: MAGIX HEVC/AAC MP4
Templates: Internet HD 1080p 59.94 fps (NVENC)

Thank you.

The correct editor transition:

The incorrect render transition:

In Project Properties/Video (tab), what setting is "Full resolution rendering quality? Your Preview window is set at Good (auto) so the rendering quality setting should be set at Good or even Best.

Though it would be expected that the render (depending on the render settings used for the chosen render format) should show what you see in the preview, the feathering setting in Mocha Pro's Video Event FX window does seem rather high at 21.77 especially for HD though of course this depends on the size of the area tracked in Mocha Pro. Even with 4K media, I would rarely go above a feather of 10 but usually less.

Another possibility - make sure that no pan/crop has been applied to the video event prior to using Mocha Pro. If pan/crop is needed, I use Mocha Pro in the default video event, render it and then apply pan/crop on the timeline to the rendered video event.

I played with it a bit and tried your suggestions. At first it didn't seem to work.
But then I rendered the MINIMUM possible prerender. Like a second of playback, and it rendered.
Then I rendered the whole clip, and it also rendered.
I don't know what happened or what I did, but for some reason it works now.

I appreciate your input, but just for reference I don't think these were the things that fixed it. I think the small "test" render did something. I don't know.

But thanks again.
