[Gelöst] form is not translated on front end

Background of the issue:
I created a form with pafe..piotnet.com plugin for Elementor. In the backend, the form is translated. But on the frontend of the site, this translation does not show. The form is placed on the page in elementor by a shortcode.

Symptoms:
Form is not translated on the frontend.

Questions:
Why is the form translation not showing on the frontend?
How can I ensure the form translation appears correctly on the frontend?
