LMN had to make a "best-attempt" at building your addresses based on your data. If there wasn't a consistent format followed, we can't make a sure determination on what, for example, is a street and what is a state. (For instance RD could be a 2 letter abbreviation for 'road', or it could have been a 2 letter abbreviation for a state or province).
Using the Client Address from your estimates, LMN made a best-attempt at dissecting and importing your estimates as leads, however you'll likely have some cleanup.
Going forward, with specific fields for Address, City, State, Zip etc., your lead information will be a lot more consistent.
