Siri is SO confused when calling contacts.

When using Siri (iPhone 6, ios 8) to make calls she doesn't work properly. This happens for most contacts I try, but here is an example:

I say, "call George Lois".

Siri says and shows on the screen. "Which George Lois?"
..George Books,
..George Brooks,
..other

I reset Siri, reset network settings, turned Siri off and then on.

When I turn Siri off and use Voice Control it will register names and calls much better. And if it matters, I have over 7,000 contacts on my phone.

Any ideas?
