Bug in out-today widget?

+++ This was previously and accidentally posted under https://developer.personio.de/discuss/622b5772aa75e6002e877363, where an image is attached+++

Hello,

please see the screenshot from the out-today widget of the web version linked to another thread (https://developer.personio.de/discuss/622b5772aa75e6002e877363).

For some users, the date is shown properly (e.g. March 22), while for others, the following appears:
dashboard.out-today-widget.freitag

Thanks!
Tom
