Border doesn't display in correct color Robhelp 2017

Explorer ,

I'm editing the Charcoal Gray layout for HTML5. I indicated that there should be a red border in the tablet view when an icon is active. It works on everything except Search. When you click Search, it's red at the top for about an inch, and the rest of the border is black. Has anyone experienced this before? I can't think of how to correct it.
