Why is panning in audio not working?

I am using Samsung J500H for about 2 years now, and I have experienced panning in all my songs until I bought a new sd card and transferred all my songs there. When I bought it, all the songs that had panning on them do not pan now, and I am really confused. Is the sd card corrupt? Pls I need an immediate answer.

P. S. I have tried everything to make it pan but it doesn't work.
