Juke box is locking hopper beneath it causing the Music disk to be stuck in a Juke Box, I discovered this as I was trying to Build and Test a New Music Disk Sorter and found after a music disc is Automatically or Directly put into a juke box it will lock the hopper below it once done playing. I would assume this is not intended as Before a hopper could pull a Music Disk out of a Juke Box once it finished previously in Bedrock.
