This is a re-post of bug MC-85806 as I feel it was marked invalid inappropriately, and I have waited for over a week for an explanation/re-opening.

If I use the following command:
/give @p minecraft:tipped_arrow 1 0 {CustomPotionEffects:[

{Id:8,Amplifier:0,Duration:3600}

]}

I would expect to get an "Arrow of Leaping".
Instead I get an arrow Identical in every way to the arrow of leaping, (colour, effect, duration etc) but named "Arrow of Splashing"
I would even have expected them to be named according to effect if they had a different duration, amplifier or were of an effect currently absent from the creative menu, but that's less significant.

This bug was originally marked invalid because numerical ids are depreciated, however replacing "ID:8" with "ID:jump_boost", "ID:leaping", "ID:Jump_Boost" or "ID:Leaping" doesn't even give an arrow with the correct effect. If I have misunderstood something, please let me know the correct way to use this command.

EDIT: The bug does not exist for standard tipped arrows as I originally believed, as the proper command for them would be:

/give @p minecraft:tipped_arrow 1 0

{Potion:"minecraft:leaping"}

however it is still the case for tipped arrows of durations, amplifiers or types not available in the creative menu.
