You will now see that item move to the blacklisted items section on the right side. Press Done to confirm your selection. That item will now no longer be able to be picked up from the ground.

In the blacklist GUI, click the red - button next to the blacklisted item's image to remove it from the blacklist. Press Done to confirm your selection. You will now be able to pick up the previously blacklisted item.
