Display error on Farro menu folder - please help

Site URL: https://klyntji.com

Hi there

I have a small coding issue which is driving me nuts and I don't know how to fix it. I have some basic custom code installed to make my menu bar sticky, which also means Squarespace doesn't want to help me unless I remove it. 

I have two menu folders at the left side of my site's menu bar. When hovering over the first "menu" and then the second "zine", it shows some text cut-off at the bottom of the "zine" folder. This text does not exist as a page. If you open the page in a new tab and only hover over "zine" without having hovered over "menu", all is well as the cut-off text does not show. I don't know where the cut-off text originates from or why this is happening. 

I attach a screenshot showing the cut-off text. Any help would be greatly appreciated. 

I see fine here. YOu can ask someone check this..
