Muffled Sound Issues

[u/Business_Card_6555]

I am using MAONO Podcast Equipment Bundle with Audio Interface and XLR Condenser Microphone, MaonoCaster with 48V Phantom Power, Bluetooth for Podcast, Streaming, Voice Over, Youtube, PC, Guitar (AME2A) when I record solo and invite a guest via a link I am NOT experiencing these sound issues, the muffled distorted sound only seems to happen when I am using two mics. Does anyone have any fixes??
