Can dual blades save points between jobs?

Guys, I hit 120 today on my dual blader, and advanced to 4th. When I try to raise 4th job skills, I get an error saying "You don't have enough SP on previous jobs" or something like that. I think my character is bugged cause of messing with saving sp from one job to another and getting sp reseted three or four times. Good game, NexonKR. Now I'm a perma 3rd+ jobber...

So, guys, I wouldn't recommend saving SP from a lower job to a highger one, at least until I/we know what is wrong.
