No logging or alerts

We have been using Norton Family for about 2 weeks.  I have been getting real time alerts about blocked sites, and every morning I can see a log of questionable sites attempted.  Yesterday (7/10) my child used the computer for several hours.  There are no alerts for 7/10 and there is nothing logged since 7/9.  I went on his account and tried to access sites, and got the popup warning about house rules, but again, nothing logged and no alerts that the sites were accessed.  I looked at his browser history and he did indeed attempt to access sites that are not allowed (of course I have no way of knowing whether he clicked through or not).  Why am I suddenly not getting alerts or logging?  he is on right now and there is no logging.
