Build Menu Icons

Heya again,
I've got my human shipyard and troll haven finished but there is a problem. When I add the Shipyard/Troll haven to my peasant/peon's 'Units Built: ' list it appears at the very top left hand of the build menu. Appearing infront of all the other buildings, and, in the case of the peasant it pushes Build Arcane Vault off the screen.

So I'm wondering if there is any way I can fix this so that
a) The new build icon appears somewhere on the second row
and
b) Somehow make it so that the peasant can still build the arcance vault aswell.

thnx in advance

I think it's these values you need to change:
Art - Button position (X) = ?
Art - Button position (Y) = ?
