Alarm icon does not always disappear from status bar

[rrthomas]

For example, just now on my phone (Xperia X Compact, Android 7.1.1) I turned off an alarm by toggling it in the main Clock+ screen before it was due to ring. The alarm icon stayed in the notification area, even after the time at which the alarm was actually due.

The built-in Clock application can't be disabled on this phone; I don't know if that might contribute to the problem.

I would really like to use Clock+ for its dark theme!

This happens if you toggle the vibration while the alarm is enabled. Afterwards you can't disable it anymore.

Please fix, I love this app because it is so small.
