Ghost accessories in HomeKit after removing HomeKit Bridge

I have some ghost accessories in HomeKit after removing HomeKit Bridge. Apple Home nor 3rd party apps allow me to remove the accessories returning an object not found error. The weird thing is that they are on my iPhone but not my iPad. I tried to log out of iCloud and log back in again, but that didn’t remove the ghost accessories. I assume they were loaded from the iPhone iCloud backup rather than from the iCloud HomeKit information.

Does anyone have any suggestions?
