Remove image description in Gallery highlights

Site URL: https://www.adamkatweddings.com/

Hello, 
Would anyone be able to help with a custom CSS for Maple Template. 
I have redone certain things on my website to improve SEO, and realised that the image titles and descriptions are shown when image is in highlight. 

please see the link:

Would much appreciate your help.

Since I did not see the description on grid, I assume you are referring to the gallery lightbox

Here is snippet to remove the description on lightbox

.sqs-lightbox-meta {
	display: none;
}
