Owntracks Invalid Object domain.object_id

I am trying to configure Owntracks. I have MQTT working and Owntrack configured. When I look at the error log I see this:

Invalid entity id encountered: device_tracker.rschapman_android-1d98f7789bd9a75clan. Format should be <domain>.<object_id>

When I pull up the states what I se is this device_tracker.android1d98f7789bd9a75clan. Where is the extra rschapman_ getting prepended from?
