LinkValidationError: Could not find Opportunity Type: Sales

Hello, when loading e-mails, I am getting the error: “LinkValidationError: Could not find Opportunity Type: Sales”.

When I see oportunity types, in https://erp.desytec.com/desk#List/Opportunity%20Type/List. I have opportunity type “Ventas” (“Sales” in Spanish).

If I load e-mail accounts list, in https://erp.desytec.com/desk#List/Email%20Account/List, and edit one that is named “Ventas”, in “attach to” option, I choose “Opportunity”. The strange fact here is that “Opportunity” appears in English, not in Spanish. Maybe that is why e-mails are being tried to be attached to opportunity type called “Sales”? By the way, all ERPNext site is in Spanish, but some elements still appear in English.

All other e-mail accounts work well.

How can I solve it?

Thanks
Jaime
