My Question or Issue

I used the feature of Discover Weekly to indicate that "I don't like this song". The Spotify app promises afterwards "We won't play songs like this in Discover Weekly.", and when looking at the Discover Weekly playlist has the song grayed out.

The song is still played, though, when choosing "Shuffle Play" on my Discover Weekly.

The UI makes me expect that this song should be excluded from being played in the current Discover Weekly, and in the future songs like this are less likely to be played.

Do I misunderstand this feature, or is this feature not working?
