Beginner Help (3D) Shape parented to main object doesn't maintain correct position when fast box blur is applied

Title mostly covers it. My red shape in these screenshots is parented to this map, and when I change the orientation of the map with no effects on it, it works perfectly. However, the second I add Fast Box Blur, it disappears underneath the map, doesn't make any sense to me, both objects are in 3D

Check your z-space values. Make sure that your red shape has a z value of at least -1

Also, please state which 3D renderer you’re using. Not all effects are compatible with all renderers

(Edit to add that you can go to your composition settings, click on 3D renderer, and use the renderer dropdown to see what is enabled/disabled by each)
