so is there a solution now? because I also have the same problem with this “gost” nodes.
In my case it is like 1 powered a node and found it trough Habmin, but then I didn’t added it as a thing.
I unpowered the device an deleted it from the inbox but if I do a search for new devices every time I get this device. But it is powered off. I also tried the way with setting as failed and remove from controller. Same behavior. I’m on the new snapshot 22.214.171.124905191822 from yesterday.
If you don’t have solution yet, I can also provide you a log if its helpful?!
