Explanation

When a Certified Messaging (CM) sender sends to an ordinary (non-certified) listener, the listener processes the data but discards the CM-specific label information. The listener doesn't understand certified messaging protocols, so it extracts the payload data and ignores the metadata. It doesn't discard sequence numbers (those are part of the label), nor does it confirm certified messages.
