New Pitch theme from Shopify is not displaying sub-menus properly

[PunkOuter]

Howdy! I thought I'd check out Shopify's new Pitch theme and saw right away that the sub-menus under the header's main menu do not display properly once you go over a certain number of items. These work find under our existing themes. I messed around under Pitch's header settings to see if I could try out different fonts and different sizes for the header menu, but nothing seemed to do the trick. I'm posting it here in case the Shopify devs or others on the forum know of a solution without having to dive into hard coding things, or if we just need to wait on a future theme update.

Cheers!
