How to translate 'This value is required.'

I am using Caldera Forms, which is great. We have a form that is in Finnish language (cloned from the same form in English), but when I do not in the required fields, an error appears on the form “This value is required.” in English.

Likewise, if I include an invalid email address, the form displays “This value should be a valid email.”

Is there a way to display localized strings in other languages?

Thanks. -Rob
