Hello! Sorry to be the bearer of bad news, but this project has been unmaintained for many years so I am closing this bug. There is though, another fullscreen application launcher called Application Dashboard, which may suit your needs. You can add it as a widget to your panel. Please give that a try and report bugs to kdeplasma-addons > Application Dashboard. Thank you!
