PhpStorm "go to" not working on local packages

Hi everybody, I'm having issues on configuring phpStorm to get the proper "go to" set. I'm working with some of my packages locally, included by a 'repositories' element in composer.json. The result is that in vendor folder I have symlinks instead of real folders (but I tried also installing from packagist). When I'm coding, if i cmd+click the methods declared in this packages anything happens, it doesn't bring me to declaration, while with files in app/ folder it works good... It's really annoing and time wasting. I'm considering (my bad) to turn down using phpStorm even after having purchased it. In sublime Text 4 for example I never had issues like this. Anybody can help? Thank you
