Grid Gallery appears very light in color

I’ve added a grid gallery to one of my pages and when I navigate to the page from a web browser on a laptop, the gallery appears very light in color and even sort of flashes a bit. Once I click on one of the images which takes me to a different page, then navigate back to the grid gallery page, the grid gallery then shows properly.

Here is the link to the page showing the grid gallery:
