The "All Tags" option is an Extension Scope, not necessarily a Load Rule which is "All Pages". I just want to make sure we are talking about the same thing before answers start to roll in. Can you verify you are asking about altering the "All Pages" Load Rule?
Thanks. There is an additional load rule that fires based on pathname and includes the relevant tags. My guess is that whoever set up the profile didn't add the tags to the All Tags load rule and had to create the additional load rule to make up for it.
