The Member Profile Screen on ClubRunner (Club or District Website), Rotary Tab, includes a field for Sponsor. Enter the sponsor name first name then last name. 
If the name does not match the Rotary.org record, it may not update during the integration process. If Rotary International feels they can figure out the proper sponsor, they will add the sponsor.
 
You can check on the integration status of the sponsor - and all fields - using the RI Integration Compare and Synchronization screen for your club members. Find the RI Integration section / link on the Admin page of ClubRunner to review / compare and then update.
