Troubleshooting preview page does not show correct explanation, so arithmetic is wrong

character with BAB +7/+2
Str 12 +1, Dex 18 +4, Weapon Finesse.

troubleshooting shows:

Attacks Rapier Melee; Number of Attacks: 2; Crit: 18-20; Crit Multiplier: x2; Reach: 5 ft. To Hit: +11 = +7[BAB] +1[STAT] +0[SIZE]
Damage: 1d6+1

Longsword Melee; Number of Attacks: 2; Crit: 19-20; Crit Multiplier: x2; Reach: 5 ft. To Hit: +8 = +7[BAB] +1[STAT] +0[SIZE]
Damage: 1d8+1

so +7+1+0 variously equals 8 or 11

Makes a nonsense of the idea that it explains PCGen's arithmetic so you can see what's happening...
