#1 - In the contacts view, it created 18 spurious columns where the title of the column is a person's name from my contact list, but the column itself is empty.
By that, I mean that my columns are titled: First Name | Last Name | Middle Name | ... |Company | Job Title | Business Phone | Other Address | Other City | Other State | Other Postal | Other Country | Doe, John | Email | Doe, Jane | Jones, Bob | George Smith | Etc. etc., with a dozen or so more random names but not ALL the names from my contacts.

#2 - In the Business phone column, all the number appear inside quote marks. SOME, but not all, of the numbers will have an additional " at the end along with a +, some will have an extra comma at the end:

EDIT: For #2 it appears to be merging the "Business 1" and "Business 2" numbers, I just wasn't seeing the whole column. But how does it know WHICH number to call???
