Attempting to refresh items on compendium actors results in error

For example, I tried refreshing "Ezren (Level 1)"'s "Staff", "Hand of the Apprentice", and "Cooperative Nature":

pf2e.mjs:1 Uncaught (in promise) Error: PF2e System | Item "Staff" (Compendium.pf2e.iconics.Actor.WNX5OQKPh4uaV7mW.Item.epNtNWhBdtOOmHYs) is its own source.

Are they in fact their own sources? That error is only thrown when the item's UUID is identical to its source ID.
