Two mails when share a folder


I have implemented a nextcloud to send reports in my Research Institute. The only configuration change I made was force_language to ‘es’.

Well, when I share a document, the receptient receive two mails, one in english with the comment and one in spanish without the comment.

We prefer in the spanish mail with the comment.

Do you know what could be the problem?

Thanks in advance.

P.D. If you want I can send the two mails.
