Atomos AtomX Cast cannot browse Files in the Overlay tab

SOLVED. Has anyone run into this issue? Having a problem when trying to overwrite a media slot in the overlay panel on our Atomos AtomX Cast using the Ninja V as a switcher. Firmware was just updated yesterday/today. Needing to input lower thirds for our live event and having no luck.

We just updated (downgraded) the firmware...🙃
