New symbols not listed in schematic editor

I’m working on a automated airflow/humidity manager with arduino for a mushroom cultivating chamber. The only thing I’m interested in is a wiring diagram. Since I can’t find most of the components I created different symbols in the local library. That said when I’m in the schematic editor I have no traces whatsoever of the symbol I created when searching the list of components.

Symbols are not listed in the schematic editor, you also need to create corresponding components in the library. And don’t forget to assign at least one category to them.
