Generated a 5 level Gunslinger (pistolero archtype) and it seems the standard view and the printer view do not show the right attack bonus.
The bonus calculates correct in the trouble shoot view
Attacks Pepperbox +1 Ranged; Number of Attacks: 1; Crit: 20; Crit Multiplier: x4; Range Increment: 20 ft. To Hit: +10 = +5[BAB] +4[STAT] +0[SIZE] +1[MAGIC]
Damage: 1d8+2;
Pistol +1 (Dragon/FirearmBullet) Ranged; Number of Attacks: 1; Crit: 20; Crit Multiplier: x4; Range Increment: 20 ft. To Hit: +10 = +5[BAB] +4[STAT] +0[SIZE] +1[MAGIC]
Damage: 1d6+2;
Handaxe Melee; Number of Attacks: 1; Crit: 20; Crit Multiplier: x3; Reach: 5 ft. To Hit: +5 = +5[BAB] +0[SIZE]
Damage: 1d6
But it does not display it correctly in the standard or printer view.
I verified prof with both weapons and my armor and I only have a light load.
I have attached the PCG file

The character doesn't have Two Weapon Fighting. Hence a -6 and -10 penalty was being applied. See the difference in the two pdfs, one is equipping for TWF and the other is not. No issue here.
