Another bug?
 

I just opened this as a ticket, but I'm putting it out here too, as I've been known to miss things.

I made a gnome sorcerer, and I think its attack/damage bonuses are off. It has a strength of 8, so it should be at -1 to hit and for damage, but it's not. It doesn't appear to be assisted by its heritage, background, skills or feats. Shouldn't the melee dagger be at +2 instead of +3 to account for the -1 from the 8 STR?

And then there's this.

Never mind, I can't upload the screen shot. But if you make a ranger, and add a bear as the animal companion, it's added as a "small" creature.

No, Daggers have the Finesse trait, meaning they can use your DEX for the to-hit modifier, not STR. Your DEX mod is +0, so a +3 to-hit for a first-level character Trained in simple weapons is correct.

This is not a bug, it's working as intended per the rules.

Cool. Thanks.

Also correct as per the rules (PF2 Core pg. 215). It starts off as a cub and grows as you advance it.

Thanks.
