Social Security has its own procedure for appointing a Representative Payee to oversee the benefits. Almost anyone could potentially be appointed the Rep Payee, so I'm not shocked that her biological father would have been appointed. From a legal point of view nothing is wrong here. So long as he is properly carrying out his role of handling and accounting for the benefits and making sure they are used for your daughter's best interest, it is likely that having been appointed he will continue to serve as the Rep Payee. If problems develop, then your daughter would be able to ask SSA to appoint a new and different Rep Payee.
