Steps to reproduce the issue:
Open Minecraft Bedrock Edition (MCBE)
Click “Play”
Create or Enter a World
Grab the following resources
Music Disk (Pigstep)
Jukebox
Place Jukebox
Enter the Pigstep Music Disk (Pigstep) into the Jukebox
Wait till the music has finished
Enter your inventory
Grab the Music Disk (Otherside)
Take Pigstep out of the Jukebox and replace it with Otherside
Expected result:
When following those steps, the game should just play the new music disk that was provided and nothing else.
Actual result:
In reality when entering a new disk it provides multible copies of the disk that you have just entered, while the other disk in my case, Pigstep has not been affected whatsoever.
I cannot reproduce this. Please disable your resource packs and/or behavior packs and see if the issue still occurs.
