i will check the modinfo but they all work for a19. have you made sure it is the correct folders you are adding to the mod folder. like valmars expanded storage then when you open it up there should be config, icon folder and modinfo.xml. but any other mods. any errors in the console or output.log/players.log.
You named the Mods folder with a capital M. And placed in the common/7 days to die folder where the exe's are.
Making one modinfo wont work becauyse you need the modinfo.xml to call that mod and it needs to be the same name as the mod it is in.
