Translate password pop up

Hi. I have your plugin on a website in four languages. Some downloads have a password. But I can’t translate the popup text that says “Enter Correct Password to Download”. In all languages it appears in Spanish (main language of the web).

With the “Loco Translate” plugin I see that this does appear translated, for example into French.

How can I change this text in each language? Does any shortcode work?

Best regards.
