Unless your daughters have the same first letters in their first names, will the computer accept such a name. If the first letters were different than what is booked, then most oneworld computers would have rejected the information.
But seeing that it was the fault of your travel agent.... let him/her sort it out. It is not your fault.
Failing that, as maybe trying to get other airlines other than AA to move points across, it may be easier to let 2nd daughter just redeem said award for 1st daughter when the time comes.
