What am I missing at character advancement (level up)?

[seiken]

Everyone leveled up in my group, and I seem to have missed something on all of their skill ranks.

For example, let's take the Wizard. CRB says they get 2 + Int mod ranks at level up. Her mod is +4 so she gets 6 ranks. I leveled her up in Hero Lab to see if I had it right, and it said she gets 7 ranks. This would make sense if I chose the extra skill rank from her favoured class, but we went with the extra hit point instead. If I select the extra skill rank instead, then the Skills tab says I have 8 ranks to allot.

So where is that extra skill rank coming from? What does Hero Lab see that I don't?

It was the same with the Cleric. 2 + int mod, and the Cleric has int mod of 0, yet Hero Lab says he gets 3 skill ranks.

For the fighter, again they should get 2 + int mod. His int mod is +1 so he should get 3 per level, yet at 2nd level he now has 8 skill ranks (4 per level) in Hero Lab.

The rogue is the only one that makes sense to me. CRB says 8 + int mod. His int mod is 0, so he gets 8 per level. At level 2, he now has 16 skill ranks in Hero Lab.

Thanks.

Which of them are humans?

[Are]

Humans get one additional skill rank per level. I'm guessing the Wizard, Cleric, and Fighter are all humans, while the Rogue is another race.

Jiggy has a point. Humans get 1 extra skill point automatically built-in.

Edit: Darn. Ninja'd the Ninja.

If they are human they get an extra skill rank at every character level.

Well don't I feel dumb now :) Yes, they are humans. That answers it.
