How to get rid of the topbar menu

Hi everybody! Few weeks ago I was trying to add a top bar menu (and I managed), but have obviously done something wrong. Please, have a look here: motherssurvivalguide.com

Under the top menu ‘how I weaned my toddler’ (dropdown) and ‘Let’s make friends’ there is ANOTHER menu! And I have no clue where it came from and how to delete it.

Please, help!

PS There’s only ONE menu created and assigned to the topbar, there is absolutely nothing else there!
