Why aren't my calendar alerts working properly - iPhone 5s

[iMore Question]

When I try to set a second alert it changes the first alert to the same time. And if I try to change the first one it changes the second one to the same time.

Try a hard reset.
Hold the top power/sleep button and the home button at the same time until the Apple logo appears, then release.
