Can you check this out @pustinek
I've decided to scratch the categories as well, people will have to adjust lol.
I can reproduce this with an extended potion of swiftness (Potion#fY).
Same behavior as in the video: Repeating /if add on the same item adds it multiple times to the filter (which is not the case with instant health for me), and the filter does not actually prevent me from picking up the exact same potion.
I'm able to reproduce this with certain potions.
Simply go into the creative menu, grab every kind of swiftness potion, and try to filter it, doesn't work.
