Right, that explains the whole thing. The mother is Lacharia Fischmann-13, the daughter is Bertha Fischmann-12. Originally the text was
[[Fischmann-13 | Bertha Chawes (born Fischmann)]]
so the mother's profile was referring to itself. That causes bold as Tommy says. Once I changed to
[[Fischmann-12 | Bertha Chawes (born Fischmann)]]
with Bertha's correct ID, the bold went away.
