The arrows at the top right, which I thought would be used to scroll through a gallery don't do so. They randomly skip from image to image throughout the album in no particular order. Is there a setting I am missing that controls this? Thanks!
There's something odd going on here. There are 51 items in the album, yet using the arrows only takes you through 11 of them. Picking another starting image and the subsequent 10 images are the same ones as before.
I was initially going to suggest running the various Gallery rebuilds but I'm not sure that will resolve it. Maybe rebuilding the Master Data on your site might fix it. I think @Chris D is better placed to advise on this issue.
