-Child A is a girl and Child B is a boy
-Child A is a boy and Child B is a girl
-Child A is a girl and Child B is a girl

There's no way you can rearrange that to get another option and no way to reduce that to remove one of the options.

And that is what I find inconsistent.
Set 1) A is the one we were told is a girl.
Set 2) B is the one we were told is a girl.
Set 3) Either A or B could be the one we were told is a girl.

Sets 1 and 2 are only different because the known girl is A or the known girl is B. If that is enough to differentiate them, then set 3 should be split into 2 possibilities.

Set 3 has one outcome, 2 girls. Sets 1 and 2 share an outcome, 1 of each. If the outcome of set 3 means it's irrelevant which of A or B was previously known, then it should also be irrelevant for sets 1 and 2.
