Ok, Thanks Jennifer.
Maybe I have a lot more reading up on this. I had assumed that because AEP was assigned a value to the eVar with in the AEP rules, that was what was setting the value to report on.
Maybe there is a step in the process that I am missing.
But if there is another step under the Report Suite processing rules, I need to find where that is because I can't see where it would be happening.
Here is the AEP rules
I am highlighting 2 examples Evar11 works, evar28 does not


And here are the processing rules which were set up originally for our first site (that hasn't moved to AEP yet, but both sites are going to the same report suite)


Or is that the issue, that this rule could be overwritting the data when it shouldn't be.
Even when you set the eVar or Prop or whatever, you can override those values in Processing Rules...
Not an "override" per se, but Processing Rules are sometimes used to set generic values to eVars (rather than sending it from Launch)... like setting an eVar to the User Agent value, or replicating values without taking up length on the Data Collection bundle.
Rule 28 looks like your culprit...
So Looking at the first Rule 10, likely none of those conditions are met, so the rule doesn't trigger.
But Rule 28, one of those conditions must be "passing", and I am sure that page.name is not being set any longer, which means it's an empty value... and that empty value is overriding the value you are sending from Launch...
You should really review ALL the Processing Rules... if they aren't needed you should remove them all so that other parts of your tracking isn't impacted. Just because Rule 10 isn't triggering now.. doesn't mean that there is some scenario where it might trigger... Keeping your Processing Rules clean and only keeping rules that are needed there is going to be much better for your implementation.. and IF you need to use Processing Rules in the future, the person who adds new rules will only have to deal with active content, and not historical leftovers which are now essentially garbage....
