group registration lists duplicate

On the following lists,
Registration List on Dashboard
Registrant's List
Manage Registrant's List (on front end)
Registrant's History (on front end for a Group registrant)
the group registration as well as the indiviual members of the group is shown. It looks as if there are more registrants than there really is. You really have to look carefully not to count either the $$ collected or the # if people by glancing at the Amount or Registrant's column.
Is there a setting to avoid this?

Hi Ellen

For group registration, there will be group billing record and group member records. I think you want to hide group billing record ? If so, go to Event Booking -> Configuration, find the config option Show Group Billing records in Registrants Management, set it to No and it should work as expected
