Enforcing time limits

Not sure if this is me not understanding what the software is intended to do, not having set it up correctly or if the kids have found a loophole....

 

The 2 kids are allowed an hour each per day on the web after which the settings should automatically log them out.  Now that the monitoring is reporting correctly (thanks to the latest update!) I see some strange entries regarding what happens when the daily limit is reach.  Yesterday web activity for kid 1 was reported as blocked at 13.44 (time limit reached) although it also shows that she was on the web subsequently.  At 13.48 she was blocked again but she continued on the web after this, until another block at 13.51 except that - well, you get the picture.  In all I see that there was around 20 'time-limit reached blocks' but it appears that she simply continued on the web for another 2 minutes or so until the next block.  There appears to be no limit to how often this can happen.  In effect there was no limit to how long she could be on the web.  Activity reporting shows the same sort of thing for Kid 2.

 

I'm hoping that there is a problem with the settings somewhere rather than this being a 'feature' that the kids are exploiting.

 

Has anyone experienced the same?  Or a fix?

 

Thanks in advance.
