Jukebox III Disappears

[iiLucky]

Describe the bug
FN Jukebox III. The slimefun FN Jukebox III, is just like a basic jukebox, but you can run more music discs and automatically listen more than 1 music. I tried to use one music disc on it, it's working but when I want to add more music discs and try to turn it on, the FN Jukebox III literally disappear, losing this one and all music discs inside it...

To Reproduce (Important)
Steps to reproduce the behavior:

1. Place Jukebox III
2. Insert multiple discs
3. Power/turn it on, what the jukebox disappear with all the discs.

Expected behavior
It shouldn't disappear and should play the music discs.
