Armory showing wrong azerite powers numbers?

Hello,
I was comparing myself to top-parsing hunters that have pretty much same gear, except for higher ilvl azerite pieces from M Cara/Nzoth.
My armory and in-game are showing that “Dance of Death” at ilvl 475 gives 1827 Agi.
Armory for ilvl 490 of same piece shows “Dance of Death” to give 2857 Agi!!

When I look up the spell on wowhead, or use SimualtionCraft and import the same character above, it shows 2101 (Which seems closer to what I’d expect).

Is Armory wrong, or Am I missing something?
