Ajuda com atualizar cadastro, consulta e gravação no DB

Gostaria de uma ajuda, quando eu entro em atualizar dados o campo somente a data de nascimento não me retorna nenhum valor e quando eu coloco qualquer data e mando atualizar ele duplica o usuário, tudo isso começou quando eu inseri o código a baixo em vermelho.
segue o código abaixo:

ChangeRegisterActivity.java
