Aero - Inaccurate Affinitys

So I was looking through my skills and noticed a discrepancy on the affinity's listed for the attack Aero. The affinity lists: CNJ (Conjurer), THM (Thaumaturge), ACN (Arcanist), WHM, (White Mage), SMN (Summoner), and SCH (Scholar). However, this is incorrect as the Summoner is unable to select Conjurer skills to select Aero. Are the affinitys correct in that Summoner is actually supposed to be able to use Aero, regardless of being unable to select the Conjurer skilltree, or is it just a typo on the skills affinitys..? :confused:
