Welcome to the Q&A Forum

Hey Guido, don't know if it's the best solution, but could be a temporary fix until the best solution is in place. I suggest to move forward with proper HREF LANG tagging or definitely delete those irrelevant languages. Try to do what I said before about validate each country/language and submit a sitemap.xml reflecting that folder to see crawl and index stats pero country/language. Add a sitemap index and obviously validate your entire domain. Just block in the robots.txt unnecessary folders, like images, js libraries, etc. to save crawl budget to your domain. Let me know if you have another doubt
