When you are looking at the wife's profile with Current name that is different than LNAB Last Name at Birth field, then you see the 'formerly' with LNAB and 'aka', with all 'Other last names'
When you are looking at the husband's profile, it shows the maiden name in parentheses, but it doesn't show any of the 'other last names'
It would be nice to see the 'other last names' when you are looking at the husband's profile, but I suspect they are not shown because of having to include all of the marriage info and they run out of room, trying to keep it at one line, if possible.
I think it is consistent, depending on where you are looking at it. It might be nice if the maiden LNAB was included in parentheses when seen on the wife's profile. They might not need the 'formerly' wording
