Problems with array printing

Parent Matrix:

public static String [][] matrizPrincipal(){
        String [] [] matriz = new String [2] [6];
        matriz[0][0] = "Robin Arryn";
        matriz[0][1] = "Lino Facioli";
        matriz[0][2] = "145";
        matriz[0][3] = "Vivo";
        matriz[0][4] = "Arryn";
        matriz[0][5] = "Feminino";

        matriz[1][0] = "Yohn Royce";
        matriz[1][1] = "Rupert Vansittart";
        matriz[1][2] = "45";
        matriz[1][3] = "Vivo";
        matriz[1][4] = "Arryn";
        matriz[1][5] = "Feminino";
        return matriz;
    }

Method that selects the names of the characters that are Feminine and are in the Arryn family:

public static String imprimeMatrizFeminina(String [] [] mat){
        int cont = 0;
        for(int i=0; i<mat.length; i++){
            if(mat[i][5].equals("Feminino") && mat[i][4].equals("Arryn")) cont ++;
        }
        String[] matrizFemininaArryn = new String [cont];
        for(int i=0; i<mat.length; i++){
            if(mat[i][5].equals("Feminino") && mat[i][4].equals("Arryn")) matrizFemininaArryn[i] = mat[i][0];
            System.out.println("Mulheres da família Arryn:" + Arrays.toString(matrizFemininaArryn));
        }
        return "";
    }

Part of main that calls this method:

case 6:
                String matrizMulheres = imprimeMatrizFeminina(mat);
                System.out.println(matrizMulheres);
                break;

Can anyone tell me why this is happening?

The second impression is correct, but why does the first one occur?

DETAIL: I'm going to have to make an impression for each family in the same method, so I'm not using the return. That is, all the Women, separated by the families.
