The Liberator PrC from Second Darkness

[Codanous]

Great prestige class, very thememy in my opinion and has some interesting kit items.

I was wondering something. It has the ability;

Lockbreaker:

Starting at 2nd level, a liberator receives a competence bonus equal to half his class level on all Open Lock(disable device) checks. He also gains this bonus on all Escape Artist checks made to escape bindings, shackles,and other restraints.

However the stat block for the character has it listed he gains an ability of Lockbreaker +1/2/3/4/5 at levels 2/4/6/8/10 of the PrC.

I am wondering if this is simply a printing error and if so on which end. Should the Lockbreaker be a scaling ability or is the stat block referring to an earlier iteration of the ability. Has anyone heard anything about this ability, I scoured around a little bit but didn't find anything conclusive. Just wondering if someone else may have heard something from when it was original created.

What's the contradiction? The description indicated that it scales at a rate of two class leves per point.

Put that simply yeah, I guess I was just way over thinking it. I'd never come across it in that form before and so I was having a hard time putting two and two together.

Thank you for helping see that, it seems so obvious now.
