Titan stat block problems

[Dark Arioch]

OK, so the stat block for a Titan says: Melee maul of the titans +33/+28/+23/+18 (6d8+28/17–20) or 2 slams +30 (2d8+17)

However, It seems that the +21 BAB, +17 for 45 strength, and +3 for Maul of the Titans adds up to +41 for the first attack. Am I missing something here? Is there some correction out there that I have missed?

-8 for colossal size.

Ahhh, thank you :)
