Alek 2.0 Navigation Error

Hi guys,

I was playing around with the - I must say - lovely theme "Alek 2.0". Great theme!
I was using some pages as primary and secundairy menu items.

There is something going wrong with this.
I know it is still in dev stage, but I wanted to share this with you.

When I create only secundairy menu items, it wil stack them on top of each other and not place them beside each other!!!
Did you notice this also or is it just me? Any clues on fixing this?

Greatings, and hopefully the final version will follow soon!

Keep up the good work.
