Header logo URL points to default language on all languages

We have had this problem since a long time and cannot find a solution.

On our default language site the logo in the header links to the correct page, EN home page, “/”. All of the other languages point to the same page. If you are on the FR (french) site and click on the logo, you should en up on “/fr/”, and on italian “/it/”.

These are my settings:

• The language is set from the directory name in pretty permalinks
• Remove /language/ in pretty permalinks
• Hide URL language information for default language
• The front page URL contains the language code instead of the page name or page ID

We need to keep how it is above, I cannot change the URL structure. I have tried to modify ?the home_url() function with site_url()?in theme but no luck.

Thanks
