why writeParcelable and readParcelable messes up the data being passed?

Question

Like the title says, I don't know why when I try passing a object that contains another object that implements parcelable with writeParcelable and readParcelable messed up the data I pass?

by messed up I mean. the ID is read by Name, and Name is not being passed because there is nothing to receive the data, and the object may or may not be passed at all.

it is fine if I simply pass Strings, Integers, Double via parcelable, but not when I try to pass an Object which also implements parcelable.

Maybe I used the wrong method? to my understanding because the object contains another object which implements parcelable, I should use readParcelable and writeParcelable. But if it's wrong can anyone tell me which method I should use and how to use it?

Thank you in advance.

here are the parcelable Objects :

First Object :

public class Absen implements Parcelable{
  private String ID;
  private String Key;
  private String Name;
  private int Age;
  private Anak Anak;

public Absen(){
    //empty constructor
}

public Absen(String ID, String Key, String Name, int Age, Anak Anak)
 {
   this.ID = ID;
   this.Key = Key;
   this.Name = Name;
   this.Anak = Anak;
   this.Age = Age;
 }

@RequiresApi(api = Build.VERSION_CODES.TIRAMISU)
     protected Absen (Parcel parcel)
     {
      this.ID = parcel.readString();
      this.Key = parcel.readString();
      this.Name = parcel.readString();
      this.Anak = parcel.readParcelable(Anak.class.getClassLoader());
      this.Age = parcel.readInt();
     }

@Override
    public void writeToParcel(@NonNull Parcel parcel, int i) 
    {
      parcel.writeString(getID());
      parcel.writeString(getKey());
      parcel.writeString(getName());
      parcel.writeParcelable(getAnak(),i);
      parcel.writeInt(getAge());
    }

@Override
    public int describeContents() {
        return 0;
    }


    public static final Creator<Absen>  CREATOR = new Creator<Absen>() {
        @RequiresApi(api = Build.VERSION_CODES.TIRAMISU)
        @Override
        public Absen createFromParcel(Parcel parcel) { return new Absen(parcel);}

        @Override
        public Absen[] newArray(int i) {
            return new Absen[i];
        }
    };

   //Setters Getters....
  
}

Second Object

public class Anak implements Parcelable {
      private String ID;
      private String Key;
      private String Name;
      private String parentName;

  public Anak{
    //empty constructor
  }
  
  public Anak(String ID, String Key, String Name, String parentName)
  {
       this.ID = ID;
       this.Key = Key;
       this.Name = Name;
       this.parentName = parentName;
  }

  protected Anak (Parcel parcel)
    {
        this.ID = parcel.readString();
        this.Key = parcel.readString();
        this.Name = parcel.readString();
        this.parentName = parcel.readString();
    }

  @Override
    public void writeToParcel(Parcel parcel, int i)
    {
        parcel.writeString(getID());
        parcel.writeString(getKey());
        parcel.writeString(getName());
        parcel.writeString(getParentName());
    }

   @Override
    public int describeContents(){ return  0;}

   public static final Creator<Anak> CREATOR = new Creator<Anak>() {
        @Override
        public Anak createFromParcel(Parcel parcel) {
            return new Anak(parcel);
        }

        @Override
        public Anak[] newArray(int i) {
            return new Anak[i];
        }
    };
}
