Reagents for Mage pet

[Klyre]

Ok so I was screwing around on a 11 mage the other day and scored 12. Brought up the Elemental fire pet (12) and tried to cast and received message that I needed a Lapis Lazuli (not sure of that gem name but close) when all references say it should be Malachite .
I checked the current P99 wiki page and that also claims Malachite.

I went and picked up said gem and was able to make pet and it was not that much more in PP so no biggie but.

Q:Is this a bug or what?
