Can’t sort numbers by creation date

It works great! however, I had a person put their number in my phone last night, but didn’t put their name. I was hoping that I could sort numbers by creation date.. but it doesn’t seem to work like that.. there needs to be a name and a number. I have several un-named numbers in phone and I can’t determine when they were created with this app. Otherwise, it’s very good.
