Pagination issue with "Support System" plugin...

Hi all. Please login - http://assistenzaweb.spin.it/wp-login.php?loggedout=true - as "***********" with password "*************". You will see - http://assistenzaweb.spin.it/ - that pagination for tickets (2 have been posted) is broken. Furthermore: why a single ticket per page? Wouldn't be better having at least few, let's say also 10, per page? Thanks, e.-
