BoldGrid followed-up with the following. It turns out it was theme related. Worked like a charm!
The Monument theme adds a border to the bottom of page and post titles by default when viewed on a mobile screen size and changing this behavior will require the use of custom CSS. I have also provided the CSS that you will need to add to remove the border from your page titles.
.palette-primary .entry-title a {
border-bottom: none;
}
Thanks for the responses. The underlines are on the other menu pages (not home). I asked in the BoldGrid support forum and they said the lines we not theme related. These are the page titles, not links.
