Gallery overlapping theme image

On one of my pages I have a solo photo then a gallery underneath. It was working fine until shortly after I finished downloading all the images. Now the gallery covers the top image and starts at the top of the page. I can not figure out why this is happening and I am hoping someone can help me get to the bottom of this.

Here is a link to the page… https://avecwanderlust.com/destinations/

I am not sure if it is an issue with the gallery or with the page. Any advice would be greatly appreciated!

Thanks,
Sasha
