All pages share a common header, which has its own page which is then embedded in each page of the website.
The common header page only has 3 items. 1 small text block, one horizontal menu for the default and 1024 breakpoints and one vertical menu for the 640 breakpoint. The menus are set to be visible in the appropriate breakpoints.
Everything appears in the Web Builder editor on screen as I'd expect (see attached picture) but, when I publish the website, the 640 breakpoint menu keeps vanishing on some pages.
I can delete it on the embedded page and re-create it and it will work, but after a while, doing other edits, it vanishes again.
This page shows the correct menu in the top right: http://kenmaynardglass.co.uk/test/contact.html
This page uses the exact same embedded page but the menu is missing: http://kenmaynardglass.co.uk/test/index.html
Change the browser width to under 640 pixels to show the vertical menu.
Does anyone have any idea what's wrong?
Thanks.
