Hello,

1) This is the default behavior the columns are set to be displayed one on mobile devices.

Therefore to display more than one in a row edit the column settings and set the width to “6 Columns – 1/2 option” from the responsive options. Then clear the cache and check back.

2) These options are available for all the menu items when you edit them from Appearance >> Menus.

And if you are unable to save custom fields then read our detailed documentation in the following link:

If you are still unable then deactivate all the third-party plugins and provide with the admin panel login details of the website to check it myself and help you out accordingly.

Regard’s.
