In order for this to be fixed, you will need to specify a custom date and time format, and use the token %V to get the ISO week number.

@NicoTanne661 you can use these settings - just as an example how I use it:
1st line:
%A - %H:%M:%S
2nd line:
(KW %#V) - %d.%m.%Y

that will come as:
Dienstag - 09:43:52
(KW 34) - 19.08.2025
