KDE: Fonts, icons and menus too big or disproportionate

I think I’m facing the same issue with Leap 15.2. As you can see, the icons are too large, same with the titlebar. Firefox text has the correct size for my resolution, which is 3840x2160

Any idea what could be done to fix it?

I use 3840x2160 KDE and a window popped up telling me to use zoom instead of editing font size. I think there is a way to reset all the font sizes to default, then in the section Display COnfiguration there is a zoom setting which I use 150% and it works fine.
