Can't set class level for pick lock

[Envisage]

As the title says can't seem to set the rogue or bard class level for the skill pick lock. I have been through the code and my tables and they all are fine. Although the skill was defaulted to 66 in the class_skill table. This is the only skill that can't be set anyone have a clue as to why? Thanks.

Actually this is happening with a few skills. Most are working as they should but sense traps is another as is disarm traps that will not set.
