alarm clock

Since the iOS 10 update on my iPhone5, i am not able to set up my alarm clock correctly.

I always use a song from my music on iTunes and even after updating to iOS 10.0.2 even though my

alarm clock is set up correctly with time, and sound (a song from my iTunes) it won't play the song in the morning.

It always plays an apple sound....it says "Seneca" but it isn't even the typical "Seneca" sound.

How can I make it work again with a my song as sound or do I have to wait for the next update because it's probably a software bug.

Please help me.
