Homepage Submenu and Homepage Menu in Mobile App and Desktop

Hi everyone, I am having an issue with the main menu on the desktop site and the mobile app. I wanted the menu bar to appear on the top in the mobile app and I thought that if I "hide" the menu items in the Homepage submenu from "desktop" they wouldn't appear there and only on the mobile app, which they do. The problem is that even though they are hidden, the empty "banner" still shows (highlighted in red) and I can't seem to get it to go away. Also, on some pages, this banner will appear completely and with the page text as in the other screenshot. 

Does anyone have any experience or knowledge of how to suppress this banner on the desktop but let it work properly on the mobile app? Just to be clear, I have tried hiding the "menu items" from desktop in the menu settings...

Thanks
