Pages - text disappears at bottom of page

Dear all,

I'm having a peculiar problem in Pages (both '09 and '13): at the bottom of every page, half of my text disappears. An example can be found on the attached picture.

This is rather troubling for all of my text is justified, and the only way I have been able to make sure my text is visible is to put in an extra Enter, which ruins the justification and leads to messy pages.

For the life of me I can't figure out why it does this. Hopefully you guys can help me!

Thanks in advance,

Nic

Edit: after removing the page numbers, the problem persists.

 

They all have standard margins: 2 cm from top, bottom and sides. Eventually I fixed the problem by increasing the bottom margin. Not the most elegant solution (there is a bit of a gap between the text and the end of the page, but at least it worked (and there was a bit of a deadline involved. ).
