Says "child is protected" but no activity

When I look at my child's activity, it only shows it for his p.c., not his phone or kindle.  Under configuration for the child, it shows all four devices he is assigned to.  Under all four, it says in green letters, "D----- is protected!"  But next to the device there is not a check mark in the Android box, just a light gray slash mark.  Same for his kindle.  The other two devices show him as protected and to the right they each have green check marks next to Administrator and his name.  He is not supposed to be an administrator.  I'm wondering if he has done something to disable tracking/monitoring on his phone and kindle, and how he has been checked as an administrator.  He spends hours on the internet on his phone, so it is very odd that none of that activity shows up under websites visited or searches performed.

Thanks for any help.
