[GAMEPLAY] Can't change the music from Updated to classic.

When i was playing a ranked game on summoners rift, i tried to change the music from updated to classic, but it still doesn't change. Steps:

1. I turn on the options menu.
2. I choose the sound tab.
3. I change the filter from updated music to classic.
4. I press Okay to submit the change. After those steps the music doesn't change, it keeps on playing the updated music. I have tried this in about 3 to 5 ranked games and its still the same.
