Hello,

Looking at the live demo of the theme, the menu appears in capital letters.

This has proven difficult to replicate, however. 
No matter if everything is put in capital letters, main items will always appear in lower case, while child items seems to pick up on the capitalization. 

Capital letters are necessary not only because they look better, but lower case letters actually break the layout. 

I trust the attachments will explain my confusion. 

Thanks,
Tobias
