iCloud Device tracker missing a family member

Hi, is there a way to do a rescan for missing family members?
I see only my wife and my other daughters iPhone.
I can see all of them via iCloud, Messages, iPhone etc.

It should add all devices. Are the devices listed in known_devices.yaml?

No, my other daughters iPhone is missing from the known_devices.yaml file.

Got it working by deleting the known_devices.yaml file and renaming my daugthers iphone and restarting HA. Now i see all family members but i get an error:

Multiple devices with name: iphone
