Final Fantasy Hacktics

So I changed Calculator's math skill to 41 All Magic and it seems to work. The only issue I'm having is that all skills in there are always already learned. I havent done much testing but is this normal or did I just miss a step? If it is normal, is there an easy work around in FFTpatcher (not hacking)? Thanks.

EDIT: Moving all the skills down like 6 slots seemed to fix this.

I'm new to this, but do we know what these markers in the ENTD do? There's also a blank one in between the two?

Then there's a bunch of markers missing or unknown in the ability section. Anyone know what the boxes under Learn with JP, Action?, Learn on Hit do? There are 5 blanks and 4 unknowns...

Sorry if its been asked and answered before, I did a forum search but couldnt get it.
