Mask is not working on Path with Warp Effect
I am currently working on a little animation. It's a liquid fall animation (red shape), that fill the black circle.
Everything was like I wanted, but ever since I've added the Wave Warp Effect the Liquid Fall animation goes a little bit outside of the mask.
In addition, there is a little gap on the edge of the workspace sometimes .
Here you can see a image of my problem.

Does anyone know, how can I solve this problem?
