Insteon JSON file has unknown devices?

Configuration
1

I was looking at my insteon JSON file and I noticed there were a lot of unkonwn devices. Is there a way to correct this and erase, update the links? I can clean up the devices I do have via resetting, but the devices in the file that are unknown… I’m not sure how to fix that.

Any tips?
Thanks

Are these devices actually still in use or are they devices that you removed? Generally unknown devices do not harm an Insteon network however.
