element 3d plugin

i recently bought element 3d from copilot and i've been using it. in the past when i would export my project, the 3d model that i created with element 3d would show up, but now when i use the media encoder to export my project, the element 3d model completely vanishes. i included a screenshot of my after effects project, the after effects project itself, and the results after i export using media encoder. i don't understand what's wrong, so please let me know and explain how i should fix this!
