Amazing Assets Wireframe Shader Probuilder Objects Issue

This problem has me stumped. I'm generating a visible wireframe using Amazing Assets Wireframe Shader on objects made with Probuilder. I can get the wireframe to appear just fine when it is applied and ran through the conversion script as seen here:

When I go into Play mode, the wireframe doesn't render and the object reverts to the solid color of the wireframe. It will stay this way even after exiting Play mode:

I know for a fact this only happens to Probuilder objects. Any suggestions that can lead to a solution are greatly appreciated.

Thanks!
