OTBI scheduled reports/analyses "From" email changed

Has anyone else noticed a change in the "From" email address for scheduled reports/analyses from OTBI?

I have rules in my Outlook to filter these to a specific folder and over the past few weeks some of the emails weren't getting moved. When I looked into the rule and the new emails, I noticed the "From" email is different for some of the reports/analyses that I have scheduled. They used to all come from the same email address so I was able to create one rule for all of them. Now it looks like there are a few emails and I just don't want to have a new rule for every scheduled report/analysis.
