Each of these has happened twice in the past four days, so we're wondering if it's just a coincidence with customers' data entry problems, some sort of automatic browser fill-in of saved data, or if there's some bug that's causing this.
1. A four-digit number appears in the company field. Once it was 1947 and once it was 1949. Birth years, perhaps?
2. A random-looking number appears at the end of the address line one field. One was 15121 and one was 3915. They don't look like apartment numbers, and they don't have anything to do with the zip code.
I can whisper transaction numbers if that would be helpful. It's not a big deal - just something that's confusing for us and for the customers, and we thought you might have some insight.
