To be completed before Dec 1 before next Faircom export.

From email:
For the Supplemental Address 1, we have 123k. Here's a SearchKit if you want to take a look. There are a significant percentage that are the contact's name again and some where it is the same as the Street Address field (these are presumably auto-fill failures on the donor's end). I could delete the supplemental address in these two cases, if that would be helpful. But overall, I mostly see apartments, PO boxes or street addresses when we have PO Boxes in the Street Address, and business names, which seem like reasonable data that we would want on letters.
