Incorrect notifications for different email accounts

Hi,

I have two different email accounts on my iPhone. Each account has different notifications settings, for example the vibration and whether or not the email displays on the lock screen. Ever since iOS 8, these different notifications will occasionally get crossed up, so the vibration for Email Account A will play for Email Account B. This never happened in iOS 7. I have tried toggling settings on and off but have never been able to fix this problem. Has anyone else experienced this in iOS 8? I can't reproduce the problem with any kind of consistency, but it happens with enough frequency to be annoying.

Thanks,

Aaron
