It's possible that the aggregated threshold is set to only display the top entity due to a configuration setting.
You can check the settings and configuration documentation for the service to see if there is an option to display an average of all entities' results for the aggregated threshold. If not, you may need to modify the code or seek help from the vendor or support team for the service.
It's also possible that there is a bug in the service that's causing this behavior. In that case, you may want to report the issue to the vendor or support team for further investigation.
I hope it will help you.
