Alright, so I changed my reminder tone to something longer (a 3 minute mp3). Now every time I have a reminder and I stop it by sliding the red x, the screen normalizes but the music keeps playing in the background. Only way to stop the music is to restart the phone or mute it for 3 minutes.
How do I fix this? It's pretty bad when this happens during a meeting etc. and I can't stop it quickly.
