I love the Enrich Data feature, but there are several issues that I've had.
1. Phone numbers are doubled in the field. In other words, a phone number will show up as (123)123-1234(123)123-1234.
2. Addresses: the street address fills with the entire address, including city state and ZIP code. Those fields also get filled, but all that's needed in the street field is... the street address.
