Double calendar notifications For some reason I'm getting 2 notifications for every 1 calendar event I enter.

I'm using Android 4.1.2 (CyanogenMod 10.0.0-grouper) on a Nexus 7.

Can someone please help me troubleshoot this issue?
CyanogenMod 10 includes an outdated Google Calendar app.

When I installed the updated one from the Play Store, I neglected to remove the system Calendar app.

Once I uninstalled the outdated system Calendar app, I only got 1 notification per event.
