Probably because none of our main editors has leveled AST yet, xD
That and our Class Template broke a little bit when HW came out, and the 3 jobs that don't have subclasses threw a wrench in how we had things set up.. Having that happen kindof pushed back our usual thoroughness on skills when they change :(
I've gone through and updated the spells now though, so they should now show up in the Cross-Class Skills section :D Thanks for the reminder about them!
