I’ve created a Remittance report in report designer and added it to an email template. The template is subscribed to the below business event:

The GI is APPayments ← Vendors ← Contacts filtered for VendorClassID and DocType = Payment. All key fields are included.
Despite this, when I bulk release payments from Release Payments, only the first record triggers and generates an email. Is this a configuration issue, or a limitation of GI based business events?
