Making menu text and icons larger

I’m very new to Kubuntu and LibreOffice (this is my third day after install).

My issue is the size of the menu text and icons is very small. I have a large monitor and running it at 3840x2160. The menu text and icons on the desktop are fine (the monitor scale is set to 160%). Looking through the other posts and I gather LibreOffice should be pulling the menu text and icon size from the system, but where? The monitor scaling doesn’t seem to affect LibreOffice.

Thanks in advance for your help
