You need to add a data connection to get the data back from the SharePoint list, then you can copy it into the main data source. https://social.msdn.microsoft.com/Forums/en-US/60434b01-d249-452d-b631-46e6490fe178/copy-rows-from-a-secondary-data-source-to-a-repeating-table-in-the-main-data-source-in-infopath?forum=sharepointcustomization shows one approach.
