Trying to download a movie.

Before the attempt to download the movie I update youtube-dl

~$ sudo youtube-dl -U
[sudo] Passwort für xxxxxx:
youtube-dl is up-to-date (2020.09.20)

xxxxxx@kubuntu-18:~$ youtube-dl --verbose https://www.ardmediathek.de/daserste/video/babylon-berlin-filmklassiker-der-20er/metropolis-1927/das-erste/Y3JpZDovL2Rhc2Vyc3RlLmRlL2JhYnlsb24tYmVybGluLWZpbG1rbGFzc2lrZXItZGVyLTIwZXIvYzRhNWRiMDItYzM4YS00N2NmLWE0ZWEtMjYyYjNjYzg1YTBi/

What irritates me is that the update call returns a version date of 2020.09.20 while in the verbose output I read "youtube-dl version 2020.05.08"
