Issue with Report SSRS Breaking/Routing

I am having issues with the automation side of one of our reports. It is a pretty simple automation where customers with positive balance get assigned to a bucket based on how old their balance is (120 days/90 days/60 days/30 days/1 to 30 days). Once assigned to a bucket (if they have an email address in the customer table), a report with the details of their positive balance is sent to their email address. We have this automation running for the 120/90/60/30 days buckets and it works flawlessly. We recently added the 1 to 30 days bucket to this automation and this is where we have an issue. The report gets generated and is only sent to the email address that is BCCed (it belongs to one of our accountants). The Customers’email addresses in the “To” section do not get populated by the automation and it remains blank when the emails get sent.This new bucket we added is pretty much a copy and paste of the buckets that do work so I am kind of stumped on why it is behaving this way.
