A Guide to Ability Learning

I can't seem to get learn on recruitment to work for Terra's Magic even though I changed the values in both C0/A182 and C2/61B9. All of my other skills seem to work on recruitment, but not that one. In fact, It still gives Actor 00 Cure and Fire, even though 00 is only level 1 and is also learning SwdTech on recruit, but the other actor gets the new spells on level-up. Any idea what's happening?

*** Just checked, Celes' magic doesn't work on recruitment either, just SwdTech and Blitz. ***
