Some rogue class skills not getting DEX bonus

[Seiken]

Hello,

I have a level 2 elf rogue in Hero Lab. Rogues get the following as class skills (among others):
Acrobatics
Disable Device
Escape Artist

With 0 skill ranks in all 3 of these skills, they all show a total bonus of 0. The rogue has a DEX mod of +3 though, so shouldn't these all be +3?

When I put 2 skill ranks in each skill, they go up to:
Acrobatics +5
Disable Device +6
Escape Artist +5

So it seems once they have skill ranks, they are getting the extra +3 (that trained class skills give), but they are still missing the DEX bonus. Acrobatics should be +8 (+3 DEX, +2 ranks, +3 for class skill).

(I actually have no idea why Disable Device came up as +6 instead of +5).

Any ideas?

Thanks.

Look on the basics summary tab, and find your character's encumbrance - is it medium? That imposes an ACP of -3.

For disable device, take a look at the Trapfinding ability on the Rogue class.

Thanks a lot! This makes perfect sense. It is definitely the armor check penalty and trapfinding.
