Windows 10 will not obey the system settings for default programs

I have gone into settings in my Windows 10 and changed the default music player from groove music to windows media player. But when I click on music files, it automatically starts playing in Groove and NOT windows media player. I have restarted Windows several times with the same results.
What is going on?

Hi, not sure if I can help but have you changed the media player for all types of music files? As well as selecting the default player you may have to deliberately change the player for the specific file type in "Choose default app for each file type". This option is found at the bottom of the default apps screen or by typing it into the search bar.

Your suggestion has solved the problem. Thank you!
