seo – hreflang region targeting – multiple regions shown in SERPS

I am a bit perplexed, with one of my websites.

The hreflang seems to be installed correctly and most of the regions are in the goal of the international guidance report, apart from the EU, since I cannot target all of Europe.

However, several regions are still indexed and Google does not recognize it in the language report

In GSC

Your site has no hreflang tags. Google uses hreflang tags to match the user's language preferences with the correct variation of their pages.

I used https://technicalseo.com/tools/hreflang/ the error was

Missing region independent link for that language (en)

& http://hreflang.ninja

The language region code does not have a separate language code

In GSC

Your site has no hreflang tags. Google uses hreflang tags to match the user's language preferences with the correct variation of their pages.

Does anyone have any idea about what it could be?
