Sorry to butt in, looks to me like the problem could be something to do with the old fashioned Sub-Grid you have used, a bit difficult to understand how it,s supposed to work for that image. if all else fails you could try sending the project file (just that page)
You should have my email address so you can send it to me without putting the project file on this forum, I could then forward it to Eric/Inger up to you though.
By the way as an aside, that floating link button thingy (TEXT US) gets right in the way of the content (cannot read all of the content)especially on mobile devices,
