Google Voice Keeps Vibrating Depiste Not Being Checked To!

[Whitechapel]

I am using Light Flow for my sounds, vibrates, and LED colors. I do not have any issues with any other apps. Google Voice continues to vibrate despite the option being disabled. It is a longer vibrate too, not something I would normally set. I've tried toggling it. I checked my stock SMS app to make sure it was disabled there, and it is, and it does not vibrate.

Any thoughts on this? The Light Flow control for Google Voice has been disabled entirely for testing purposes until I figure out what is going on.
