Base Attack Bonuses

[Oracle68]

Hiya!

I just wanted to ask why the base attack bonus box on the standard D20 character sheet will not show all base attacks? Example, a 14th level Barbarian has 3 attacks. The box only shows the first attack.

Is there a reason for this?

And before Wayfarer<--friend who disagrees that this should be an issue - pipes in, Yes I know all one has to do is look at the Unarmed weapon line.

Thanks!
