You can try to delete the DUO camera on your NVR monitor. Then add the camera back and a*sign 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-.
