The Uldum Accord Supplies is misformatted in Categories.lua

Current:
n(-169,{q(58097,g({repeatable=1},{i(173283,g({b=1},{aze(35,{rank=4})})),i(174484,g({b=1},{p(2850,{itemID=174481,b=1})}))}))})
Fixed version:
n(-169,{q(58097,g({repeatable=1},{i(174484,g({b=1},{i(173283,g({b=1},{aze(35,{rank=4})})),p(2850,{itemID=174481,b=1})}))}))})

The key is to have the supplies item containing the Azerite Essence item, instead of having the Azerite Essence item just a reward from the quest (which isn't how paragon caches work). I tested the fix myself and it shows up properly when mousing over the reputation entry like it would for other reputations. I only noticed this because I was certain Uldum Accord Supplies had 2 things in it, not just the pet.

Categories.lua is actually generated automatically from files which are actually readable :)

But your point is taken and I see what you mean, so it will be adjusted.
