It shows any records created by staff as well. You’re right for the log.
From what I see, the template is ready to display the granter name, but the code expects the payload (creation and listing) to include a list of users so the name can be figured out based on the granter ID. I think it has never been implemented.
I was never able to find a breaking commit so I’m unsure if it was a planned feature that was never implemented or a bug Either way, I figured that the UI seemed to have the explicit intention to have this in place (going by the Granted By column header) so I opted to go with FIX.
