I have this on Daniel Garren profile and I am not sure why. I have added sources. Can someone look into this please?
Beth, as you haven't provided a link to the profile in question, I can only give a general answer: It's because somebody has added the {{Estimated Date}} and {{Unsourced}} research note boxes in the Biography field of the profile. You may remove one or both of those boxes when you feel that the profile is properly sourced, and you've got at least a calculated birth year based on an approximate age given at a specific date.
