[SOLVED] Submenu dropdown covers rest of submenu - how do i get it to the right?

Hi

I just updated both Wordpress and the Atahualpa theme and my menu got a bit screwed.
Previously, i would have a submenu with a submenu to the right of it, indicated with a small black arrow. I know where to change the the color of the arrows.
Is there a way to make the dropdown submenu appear to the right of its parent, instead of putting itself above the parent (which makes the rest of that menu unreadalbe).
See attachment.

Thank you.
