Bug with Rattay's hunter quest

I have a problem on this mission:
I catched two birds but when I dropped the 3rd trap, it was shown on the map with a “B” icon.
Then, i took the birdtrap again but the “B” icon was still here, I dropped it 10 m. around and a “C” icon appeared. I think I also moved the trap a bit by walking on it but now the “B” and “C” icon are still on the map and radar and I can’t find back the 3rd trap despite the time I looked around for it.
(I’m on ps4) is it possible to add more traps in berthold’s (i think this is his name) inventory so I can finish the quest or cancel it to start again ? Thanks a lot if you do!
Love your game by the way, good job!
