Sometimes it just takes a little while for all the images to show in your scrolling gallery (especially if they were listed within the last 12 hours.) EBay has to re-index all listings when they are submitted. If you are a new seller, that process can take even longer.
I just checked the scrolling gallery in one of your listings and see all of their images, so it appears that it is now caught up.
