Landscape format doesn't work, Querformat funktioniert nicht

Writer Version: 5.1.6.2, Win 10 /64 bit,
When I go to format, page and choose landscape it doesn’t change anything. I alos tried to change it in printer adjustments and it didn’t help.

What can I do? Thanks for any help!

I found out myself: The tools at the right side got the menu in the lowest line “orientation” “Ausrichtung” to choose portrait or landscap, and that works!

Format - Page should do the trick. If it doesn’t for you, there’s probably something wrong with your user profile.
