Phantom new camera notification on UNVR?

I recently set up my UNVR and moved all my existing cameras to it.

Yesterday, I added a new G5 Ultra turret to the mix, and everything went fine.

However, after successfully adopting the Ultra, I am now frequently getting a "New device detected" notification:

Sometimes the notification disappears after a second, sometimes it stays up for a few minutes. If I click "adopt," the Ultra I just added flashes orange for a second and turns green again, but it never disconnects or stops recording.

Is there a way to stop this notification from showing up?
