Only thing I can suggest is the usual restart of the iPad. I've been using Pages a fair amount recently, and have not noticed an issues.
The last update to Pages was three weeks ago, so unless you've been living with this for a while, it's unlikely to be a new bug.
Note: Force quitting the app is probably sufficient, but I almost always recommend a restart because I know I often fail to restart mine as often as I probably should (about once a month seems to work well).
