Many of the users in this forums don't are developers, the support is voluntary.
NOBODY here knowns everything neither have all the hardware in the world to make test.
You don't say what applications you install, maybe don't have a .desktop file or the .desktop file contain lines like
NotShowIn or
OnlyShowIn, check as root with a text editor the .desktop file of the application (in folder /usr/share/applications)
I also ask a question and make a suggestion that you don't bothered in answer
