Why no record hint for birth source?
Without any marriage or death detail being attached to this ID, the hinting algorithm has produced correct suggestions for both these events. However, in spite of the birth detail being inputted, and there being a source to attach to match, this does not appear under Research Help. I have found this to be the case whilst working on siblings of this the individual, over the past couple of days.
Using the link, via the FamilySearch logo on the Person page, the birth source appears as the first item on the Results page, so why doesn't the Hints algorithm lead to it appearing on the Person page?
(Naturally, I will return to this profile later to complete the missing data and add more sources.)
