AX7501-B0 Parental control missing

Jadams

Hi, 

AX7501-B0 with firmware V5.17(ABPC.1)C0

When using Parental control the only thing I can do is add a profile, select devices and time / day schedule but there is no option to add URL’s for blocking etc as per the instruction manual. 

The option in security isn’t there.

Thanks.
