Pull Down Menus Vanished?

Hi,

I was having a lot of problems with the very latest LibreOffice Calc (5.1.4?) on Fedora 24 (LXDE), as it was crashing constantly. Thus, I downgraded the version installed down one version (5.1.3?), and it works perfectly except for one thing: All the drop down text menus have disappeared and I can’t work out how to get them back! Does anyone have any ideas? The icons just don’t do all the things I need!

Thank you for any help or comments received!

OB.
