Looks like you are still running the demo line item on your account that is pre-populated for you to use in testing in the pre-release process. You should locate the line item and pause it. This will stop the delivery of these ads but please make sure to add new networks and line items for the delivery of new ads to start coming through. If you would like to get access to Marketplace, you should also reach out to email@example.com with the full store URL included for your apps along with the settings page up to date with payment details.
