Cannot resolve symbol 'category.repository'

[d-i-sBouadim]

in the services.xml file I get errors for all entities repositories ( category.repository, product.repository ...)
But the code is working so I know it should not make an error.
The problem is also that I don t have autocompletion for this entities.
All the rest work perfectly as you can see in the screenshot.

Actually when I try autocompletion on "repository", phpstorm suggests me only this : "mail_header_footer.repository", which I never use...
I also want to say it was working, but not anymore since few months. Cant remember exactly.
I invalidated the cache in PhpStorm, I even uninstall, re install.
I contacted PHPstorm Support and told me to try my luck here.
