Links in the menu not clikable

I added a menu to my site but some things aren’t right. The menu items show up but the items can’t be clicked. When checking the html of the page there is no “a” tag to be found in the menu area.

link to my website:
wordpress version : 4.8.3


You can try to use the following CSS code.

You can add CSS code in Dashboard → Appearance → Customize → Additional CSS.

#content {
    position: static;

Please feel free to ask any other questions that you might have.

Kind Regards, Roman.
