To fix a problem in a wp slide - repost

Hi, i need to fix a problem in my website. The problem is this: the theme has a slide. At the beginning the slides were 4. We changed the number of slide working on the code of the theme. Recently we update wp to a last version and the problem start. If you look our home page ([login to view URL]) you see only 4 slide. Insted in the theme controll panel there are 7 and more slide that you can set up. What I need and resolve this little problem because in the home we need more than 4 slide! I need olso some little improvement like - I wuold like to have more sidebar and choise it for different pages. Now I have the same sidebar on every pages. I wuold like to have different sidebar (and topic) for different pages. look the sidebar here [login to view URL] . For example in the profile have an interview, in the background have a video, in the contact have a map...etc. -the sidebar is in italian and english because i can't to have two different sidebar for italian and english version. For example soon there will be a chinese versione. I need to fix this problem. I need different sidebar for each language. This is all! Thanks!
