Character sheet problem please help!

Hi, we have a problem in the Iron Kingdoms campaign we're playing. Currently the character sheet do not allow to change the tab, we can interact with the one page that was open at that time but the players cannot change the tab afterwards. That had never happened, if you have a solution we would appreciate it. Sorry for my terrible English, I'm using the google translator. Thank you for assisting me.
