Gallery image sort

I have set image order to alphabetical in the galleries tab of the settings section, but form some reason the gallery refuses to start from image KP-STUDIO_0001 and starts from image KP-STUDIO_0029. As a result the first images 1-28 are on the last pages (9-11). Besides that there in sorting problem, but it is important to show the images in the correct order.

The page I need help with: [log in to see the link]
