My in-game music seems to play more than once at the same time on iOS yet the blueprint settings seem fine, why is that?

Am working on an IOS game, it works (sounds) fine in the editor, but tends to error when deployed onto my IOS device.
After multiple game restarts, the game music seems to play more than once at the same time. It is fixed when I restart again.
It happens once in a while and I have still failed to fix it . I have tried to stop, pause (and even destroy) previous audio components on restart, and then create new ones on BEGIN PLAY, but it still seems not to have fixed the issue.
What could be the reason behind this?

Any suggestions are welcome. Thanks in advance.
