Norton Family cannot configure 2 identical tablet devices (Android)

My 2 kids have 2 identical Android tablet devices.

First I configure Tab1 to Kid1, then I see  --->    KID-1 assigned TAB-1      KID-2 assigned NONE

Then I configure Tab2 to Kid2, then I see --->    KID-1 assigned NONE      KID-2 assigned TAB-2

 

Seems like NF cannot configure these 2 identical tablets with different name to 2 different kids at the same time.

Please advice on how I can resolve this.
