This has been known for ages. Years even.
What you can do, is swap from "normal" soundtrack to "family", or "family" to "normal" and then back again, quickly. This is one of the workarounds that I've seen work.
Also, what I've seen, is that you Explora has to be paused for an amount of time in order for this to become the case.
Sadly, it seems this bug is still with us after all this time.
