I use LibreOffice that a few years ago forked from OpenOffice.
On the bottom right hand corner you should have some little icons representing the view. Just click on the 1 page icon. That should do it.
If you cannot see the bar, activate it by going to VIEW - STATUS BAR to activate it. (It should have a check mark beside it, if it does not, just click it once)
