There's an unwanted white row under the Header when hovering the Header menu.

Hi,
So far the experience with the theme has been smooth, nevertheless, when hovering the main menu on my site, a white row containing a subcategory on it, displays under the header.
When first importing the Fast News Demo, this issue is not visible, but as soon as I select our Menu the issue shows up.

Here’s the link to our Website: https://www.justfocus.fr/

Please go ahead and hover over the main menu and you’ll see that white stripe with a red text sub-category to the left.
We don’t want it there, We want that sub-category to be together with the rest. Just like the Original demo is presented.

Thanks in Advance.

I FIXED IT!!!!

I followed the instructions on this link: https://forum.tagdiv.com/mega-menu/

I created a new menu but did not include the subcategories with them. Changed the “Not-mega-menu” with the specific category for my menu and that was it. No more white stripe!
