Failing to Render Proxies for Alexa Mini LF Footage

Hey! I'm currently trying to render proxies for Arri Alexa Mini LF footage. It allows me to render the shots that do not have an audio file attached, but any clip that has the on board audio from the camera attached fail to export through media encoder. Any one with a similar issue or know what could be going wrong?

My computer and premiere are both on the newest updates.

Thanks!
