Resolved. It was an issue with an image that was 10 pixels larger than the maximum size allowed for the width of the column
Ah, I also would like to add that I am trying the various widgets that may help me to display the menus as I want (e.g. Accordion menus, toggle menus etc.), but so far I have not found the plugins that display the menu with a style that I like. Therefore, I accept also plugin suggestions!
