The Quest Reward "Select a Reward" window tab when a collection item dispenser is used says "Ornamentation" instead of "Collection".
Could I get more detail on what steps you took. What specific item (Full name please) you are speaking of. I made a check and the data looks good on the items.
When you accept a reward from the overseer system that has a collection item as a %chance reward, when that chance succeeds it instantly gives you another reward to claim. The window title for this claim is wrong. There isn't an actual item at this point.
