Items only player 2 can pick up?

So player 1 will go to pick up an item that is dropped by a monster/ found in chest and when the item is being picked up by player 1 (by pressing A) - the said item immediately goes to player two’s inventory!!! Everytime!! Why is player 2 getting all dropped items??? This sucks me and my BF love to play we started a new seasonal game today and again we were reminded why we stopped playing before (I wish I had sent these issues to blizzard then but I am now) and it’s because my BF (player one) never gets an item, I get the items (player 2 here). Also player 2 cannot drop the item to have player one pick up the item either. Please tell me how we can fix this!!! I want to play :sob::sob::sob:

Are you playing on a console?
