Why are Google results for my brand in mixed languages?

Hello,

When I type the name of my brand into Google Spain, I get this result that mixes the pages of the versions. My site is available in Spanish, Catalan, French, Italian and English.

Does anyone have any idea what could be causing this problem?

Interesting. 

Do you have any complaints in Google Search Console?

Your site does have hreflangs and they look kinda valid

If I click Advanced Search and select Language: Spanish all results are indeed in Spanish.

Could it be that Google simply shows most popular results from your site regardless of language?

No, there is no way to specifically control the language. Google chooses sitelinks.

Yes, that's probably the case, thanks for the link.
