Background: If an address has a company Name associated with it, you can choose "Company" from the Company Type field to force CMS not to display the contact name on any correspondence to that address (labels, letters, etc.).
If there is no company name, the Company Type field is disabled.
Bug Description: After removing the company Name, the Company Type field remains disabled but the field still has "Company" in it, causing the correspondence to that address to be blank.
This bug has been corrected in version 9.9.23.
Workaround for older versions: Type in anything in the Company Name field, change the Company Type field to "Regular", then delete the company name.
