Appointments+ does not read all translations

Appointments+ does not read translations for shortcodes app_schedule

I have translated Appointments+ into Danish using Poedit. However, my translations for the app_schedule shortcode do not show up. Everything else uses my transalations correctly.

My shortcode
[app_schedule title="Ledige tider fra START til END" logged="Klik på en ledig tid for at reservere"]
