Newly installed M9 Deco network

3 kids set up under parental control - 1 Child and 2 Pre-Teen Filter level.

Malicious Content Filter ON

Intrustion Prevention System OFF

Infected Device Quarantine ON

Problem: one of the Pre-teen accounts is sending notification "Parental Contols Name attempted to visit Facebook" every 20-50 minutes or so.  Even when I can see the single device associated with that kid is turned off and she is outside playing netball.  She doesnt have Facebook, the only social media she has is ticToc (was musically)

Also what the hell are Occupancy Tags?

Any ideas?
