When you add a deliverable to a campaign yourself, it shows up on the report under your own name — you’re the one who added it.
If you’d rather it show up under the influencer’s name instead, you can reassign it:
Click on your name under the assignment.
Click the three dots (⋯) in the upper right.
Select Update Name.
Change the Display name.
Click Update.
Reload the report, and the deliverable now shows up under the influencer’s name rather than yours.
