Working on IRN 1005638, and when adding "Ruel P. Tolman [1879-1954], Washington, DC", the software shifts the record directly below it in to the the location field, and inserts a period at the end of DC, and duplicates the last party in the record.
I tried it on a different record, and it is the phrase "Washington, DC" is where we're going wrong. I changed the party name and kept the "Washington, DC" and it still happens.
Also happens regardless of tabbing or clicking.
