NPC Mod proficiency points - how do i change them?!

Hey! ive been using DTCLEP for the first time to override certain NPCs and change their class/kit etc. So far working well however i cant seem to alter proficiency points.
Basically made Xan a Blade to make use of his Moonblade. Hes due an extra point but i cant add it in (other than through EEKeeper ofc). So how do i do this?
Also any suggestion on where i should put said point are appreciated!

Thanks!
