Having the images flush on the top

Each of the images in the grid has a <p> element above it. If you can, get rid of that. If not, this CSS will hide it:

.card p:first-of-type {
    display: none;
}

To add CSS: use the “Additional CSS” option in the customizer. https://codex.www.ads-software.com/CSS#Custom_CSS_in_WordPress

Learn to use the Chrome Developer Tools to help you see and test changes to your CSS.

Weird can’t seem to find that <p> element.

Appreciate the help though @sterndata thank you very much!
