Kde systray icon apps

My systray doesnt show external apps icons such as keepass. I have only default kde system icons and nothing more. Few days ago everything was fine. Apps are running, processes are visible, but no icons in systray. I was trying remove systray or all taskbar but no results. Other users doesnt have this problem.
Im running kubuntu 19.10, kde 5.16.5. What can I do?
