Delete a device?

I have a simple Home Assistant setup, but an issue arose today and I do not know what to do.

After doing some updates (shown in Notifications), when I clicked on the ESP Home tab, I was shown “Supervisor: Unable to fetch add-on info to start ingress”. While doing the updates, I was warned that a device had the same ID as another (it was experimental), so I deleted it. Also, one of my two ESP Home devices did not update.

When I go to Settings->Devices & Services->ESPHome, I see 3 devices, but one of them is a left over from the device I tried to delete. I suspect that if I delete this device, then everything will be fine; but I have no idea how to delete it. Help!
