Navigation Parent Page Not Working - After Theme Change

[luckie77]

Hello. I recently changed themes on my Shopify store account; moving from the DISTRICT theme to BERLIN. Since switching themes my navigation parent pages no longer work (HerStory, Our Story, Shop), although the dropdown menu/child pages remain functional.

Nothing changed on my end as far as the menu setup; I just switched themes. Any idea of what could be the bug and how to correct it? It appears BERLIN is a new theme. I'm not finding any support notes anywhere.

Thanks.
