Certain Loot in COOP is open to all players when meant to be seperate

Been playing coop and have noticed that when Belts and I believe Amulets drop, they can be picked up by either of us, whoever gets to it first, while everything else is assigned to a specific player and greyed out for the other. A minor issue, but it's annoying when my friend scoops up two heavy belts in one map.

This seems to be sorted , Belt drops now seem to be exclusive to only one of the players. Might have been an issue with our Loot filters.

Or maybe it was all in our heads, as we seem to be the only ones complaining about it (i swear I'm not crazy).
