Problems with Image Galleries

I have this problem where images appear to far right on the screen when sliding through them with the carrousel slider. Before the update, the images would show up nicely aligned on the center of the screen.

I use normal WordPress gallery (no widget) and have tried editing media, recreating galleries in new pages, aligning gallery on page but nothing. I have gone through all updates. The same problem on all browsers, even while logged in to wordpress site. Have not checked mobile though.

Check out one of my pages and slide through the gallery to see what I mean.
