Timeline render not matching Preview

Hello, so I am setting up a ‘three section wipe on’ effect and I’m not getting the same result after I render the effect as I see when it’s previewed. Rendering the effect is changing the effect. I’m using a mask on a video layer, over top a color layer with the same mask expanded to give an outline. I’m then nesting that to wipe on both layers. I’ve done this one three different times on three different layers but one of them does not render properly. I substituted blue here for my video to make it more clear. 

Here’s a still of what I see previewed before I render.

And here’s how the render turns out. 

Here is the same effect being done on the next layer correctly. 

I’m using version 24.5.0 on Mac osx 14.2.1 

Thanks.
