In the "Combat" section of the creative inventory there several tipped arrows that shouldn't be there:
Tipped Arrow (awkward/empty/thick/mundane potion) 4 times
Arrow of splashing (water bottle) which has no effect
Non-extended effect versions of every regular effect shouldn't be there either, after all it's the same for enchanted books: There's protection IV, but no III, II or I
They are diffrent, 1 is awkward potion, other is uncraftable, etc
The arrows just exist in every type there is a potion of, intended
