I do not know if anyone ever had this problem or knows how to solve.
I edited the Lancer job, I changed the skill set, and when I play with him all the skills already are open.
Lancer, Ninja, Geomancer, and Mime are all extremely uncooperative when editing. Geomancer is a bit more cooperative than the others, but... you're generally better off leaving these alone if you're trying to make new jobs.
It is more complicated than that, check my thread.
