Agonizer 9K - Loot Drop Glitch?

Just did several runs hoping for dictator or white elephant. Was split-screening and noticed that on every run (did about 8 or 10) all items dropped were exactly the same for both characters.

Notes: Game is not coop-etition. An item can be picked up by one character, dropped, and the other character will see two copies of the same gun.

Also - left Agonizer and tried a quick El Dragon kill. This did not occur with him or any of the mobs killed in the initial area of Jakobs Estate.

Is this intended for Agonizer or an unintended glitch? Anyone else encountered this?
