Hi Howedennis,
I just looked at a few of your active listings and I was able to see 16 listings in your scrolling gallery in those that I viewed, but I'm not sure if I looked at the ones you are referring to. The only thing I can think of that might be causing some of your listings to only show a few items is if those listings contain scrolling gallery code associated with a different Auctiva account you have used in the past.
In any event, if you are still experiencing this problem, I recommend contacting our customer support team using the form on the following page of our site:
