Number of sources
This is referring to the Person Page.
I merged 2 records Andrew S. Harrison LZZD-18Y and Andrew St. Clair Harrison. GQXS-JRS. The latter was the remaining record. The former had several census records (containing his birthdate), and the sources did transfer. However, the Birth field still says there is only 1 source for that Birth.
I have tried reloading the page several times, but no change.
Ever since the new Person Page was released, there has been a problem showing sources for the Residence field. That has never been fixed.
These notes are important! They are the best way to tell if the information is supported or not! If it's not going to show the truth, at least don't show anything at all.
(btw, I have no idea what the required "Categories" for discussion posts are about.)
