Hello when I use redstone, the disk c418-11 is played, and when I break the jukebox the song continue playing, I played on 1.20.1

it's append when I check use legacy datapack

The legacy datapack doesn't work with redstone and has some bugs. You can still generate legacy packs for backwards compatibility, but you should try to use the new datapack which works much better and fixes both of the problems you're having
