When printing letters for most references, the full address did not place a comma after the city. The problem lied in the fact that the city, state, and zip are concatenated to a separate column which is used in the report and the concatenation did not apply the comma. This has been resolved, the concatenation process is only activated when the record is created or saved with changes. Therefore, it this is important to you, open the record for the reference in question and make some incidental change and save the record. Note that the USPS’ preferred formatting of a postal address is all caps and no punctuation.
