If I may, what Minty means is that what you're looking at isn't actually a record as denoted by the asterisk/star on the left. If you look at the table, that value won't be there unless you've done something to cause the record to be saved. If you don't want to see what you're seeing, remove the default property setting you have for that field.
@Minty; sorry if I've misinterpreted what you wrote.
The more we hear silence, the more we begin to think about our value in this universe.
