english menu updates also updates french menu

Hello,

I created an english header which should be the translation for french header. I edited this header by inserting my english menu in it. Problem : it also affected the french header (and inserted english menu in french header). When I put back french menu inside french header, then my english header contains french menu.

I can’t really show you anything on the live site because it’s not yet bilingual (I’m just making tests in the bo because all pages are not still translated).

I also work on my local site and the issue is the same :

When I edit english header, it updates french header also, and reciprocally.

Do you have an idea of what the problem might be ?

Thanks in advance for your help.

Best regards,
Brian
