Updating data in a new linked field

I have added a new linked field in a table. It correctly populated if I re-select the key field but not otherwise. Is there any way to force all members of the table to update?
It is the field S 2020 Sponsor in the table People which should populate from Organizations in the database CCE2.

Hello,

Do you mean that you have added another loaded field in a link&load set and you have to re-select the key field to have the new loaded field to populate correctly? In the design mode, click to sync this set of linked fields with updated source values of all records to populate values on the newly added loaded field. You can refer to this document for more details.
