I played around with metatags and when i revisited those pages they now have description metatags. Not sure what the initial problems were though. Sorry for the time waste.
Layout is not Content, it is not used to create pages, so I think you have chosen the wrong way. To avoid problems, just need to use every tool for its own purpose. This is not a direct answer,...

I guess because the CSS code that manages this element is:
.block-hero-no-image {
background-blend-mode: luminosity;
background-color: #0074bd;

background-position: center center;
background-repeat: repeat;
}
The background-blend-mode CSS3 property is not supported by Microsoft browsers:

I would recommend to use another CSS technique for this block - for example CSS opacity or RGBA color.
Or may be simply color texture.png file.
