I am trying to understand what you were doing. You crated a dynamic template and added it to a post page of type gallery? Or did you just paste the gallery html code right in there. Because the gallery code looks strange with '<br style="clear: both">' which is not native to Kriesi I believe. Or you are using child/parent page properties to create 3 pages with 1 image each all children of the original gallery page?
So you need to stop adding gallerys the way you have been doing before since it's not working. I had no problem creating a gallery by first creating a dynamic template with a slider component. The page which with have the dynamic page should have all the images that will be part of the gallery displayed on that page.
Please look at the settings http://i.imgur.com/lM6vpX1.png (post or page) ... end result ( http://i.imgur.com/QWOtbUL.png ) it shows the gallery as a slider but click on each image ill bring up a lightbox and have next, prev buttons inside along with only the images that are part of that gallery.
