Help Droid Turbo Voice Commands Issue

I had a Droid 4 paired with a BlueAnt Bluetooth Q3 headset. It worked great.

In my directory I have a "Dianne" and a "Diane M". Depending on whom I was calling all I had to say was "Call Dianne" or "Call Dianne M" and it would make the appropriate call.

I recently replaced the Droid 4 with a Turbo.

Now every time I try to "Call Dianne", it keeps asking if I want to call "Diane M".

I like the phone but it is quite disappointing that voice command on Jellybean works better than KitKat.

Is this a flaw or am I doing something wrong with the new phone?
