Need help figuring out my tiefling bloodrager claw attack

[Doug Maynard]

I'm confused about how things come together with my character's claw attack. He's a 3rd level small (halfling-sized) tiefling bloodrager with the abyssal bloodline. When raging, Herolab lists his claw attack as:

Claws x2
+4 (1d3+2)

But with the following stats while raging...

- Small size
- BAB +3
- Str 20 (+5)

It doesn't seem correct to me. The attack is:

BAB + Str modifier + size modifier
(+3) + (+5) + (-1) = +7

Shouldn't damage be 1d4 not 1d3 based on the bloodline power listing ("These attacks deal 1d6 points of damage each (1d4 if you are small) plus your Strength modifier")?

And shouldn't the damage modifier be +5, not +2?

Please let me know what I'm missing! Thanks!

The scripts in Herolab are wrong, for example if you level the same character up to level 5, the damage die increase is kicking in instead of at level 7
