Wells automatically to top of page when I click out of an image in a gallery

Help Squarespace friends!

I'm redesigning my site in wells and having trouble with the galleries. When in a gallery, if you click to enlarge an image and then click out, it pops back to the top of the whole gallery instead of staying at the point you've scrolled to. I thought it might have something to do with a bit of custom CSS I added in, but when I removed all of it and checked it out, the problem was still there.

Couldn't find an answer for this anywhere online, an insight would be appreciated!

Cheers,
