I can't align my photogallery

Hi there!

I’m trying to alling a photo gallery in the beaverbuilder theme.
When I’m on a wide desktop, the photo’s allign on te left side and leave a gap on the right side. When i’m on a "normal desktop they are perfectly in the middle…

How can I allign the images in teh gallery so that it looks good on every desktop?

Hopefully somebody can help - thanks in advance!
