Keep between levels option

I wanted the music in my game to go through levels and I saw someone suggesting to use the “keep between levels” option in one discussion. But it doesn’t work, the music restarts when I enter the next level and it glitches and when I open the editor there are like 4 music blocks in every level. I have to delete them all and turn the “keep between levels” option off.

Here’s link to my game:

Restart the editor and go to the level where you added it, and turn that off
