MangoHud displaying the wrong GPU in SteamOS game mode

Is there a way to configure MangoHud (or is it MangoApp in game mode?) to display the correct GPU? It’s displaying the stats for the integrated GPU in my CPU (Ryzen 7600X) instead of my dedicated GPU (AMD 7900 XTX). Adding ‘pci_dev=0000:03:00.0’ in /home/bazzite/.config/MangoHud/MangoHud.conf’ isn’t working. I’ve also tried that in both presets.conf and mangoapp.conf.
It’s annoying because it was displaying the correct GPU a few days ago. I think a Steam system update might’ve broke it somehow.
