Connection Blocking

I have Norton Security for Mac 7.0.1 installed and find that while application blocking seems to remember the applications that are allowed or blocked and do not ask permission again, I find that the pop-up's asking for permission to connect to the internet from the Connection Blocking function never seem to be saved even if I choose 'always use this setting' etc. and come back regularly.

Any suggestions ?  Do I have a setting wrong ?
