Apple Music Profile shows on multiple devices and I cant separate them

Hi,

I have the same apple music profile on several devices, with different AppleIDs being used for each device.

Any change to the profile on one device makes the same change on the others, and deleting on one deletes it on the others. Creating a profile then adds it back to the other devices as well.

I've tried disabling Sync, following another suggestion, but it doesn't break the link, and reenabling it copies the playlists etc. back to the device.

Hope someone can point me in the right direction to fix this.
