Hi, we have a service space that, by default, is in spanish. We have mostly spanish customers, but we have some customers that we will support in english. We did set our portal in english and we enabled language support in english, available to customers. We also have email templates translated into english:

But I did a test and, event if I use the portal in english, write a request in english, etc, I received an email notification in spanish. I checked also and the request was created correctly in english:

How can I enable Jira to send this email notifications in english? Also, is there a way to always send english email notifications to a certain set of customers? The space default must remain in spanish.
Thank you
