As you can see here, the Last Name fills the First Name section even though I have the game set to use First Name - Last Name. It does this for both Adopt or Medical Birth. Regular births do not autofill any names for me from what I’ve seen, and I think changing Adopt and Medical Births to do that would be the easiest way to fix this issue.
If you manually enter the names — for example, Sadie in the first name field and Oswald in the last name field — the name will display correctly in the First Name – Last Name format.
However, we understand that the current autofill behavior can feel inconvenient. We appreciate you pointing this out, and we’ll take a closer look at it.
