You can try to delete the DUO camera on your NVR monitor. Then add the camera back and assign another channel for the DUO.
This is the guide to delete the camera on the NVR, https://support.reolink.com/hc/en-us/articles/900003769346-How-to-Delete-Offline-Camera-Information-on-Channel-Management-Page-via-Reolink-NVR-New-UI-.
