Xamarin Forms Firebase DeleteAsync 逻辑 - 为什么删除第一项而不是第二项？

Question

在我的代码中做的事情是当我删除第二个块而不删除第一个块时，要删除的是第一个而不是选定的第二个块。"

    //This is where the listview item tapped
       var certification = args.Item as Certifications;
        if (certification == null) return;

        await Navigation.PushAsync(new CertificationDetailsPage(certification));
        lstCertifications.SelectedItem = null;

    // This is the code to delete
       var toDeleteCertification = (await client
            .Child("Table => Certifications")
            .OnceAsync<Certifications>()).FirstOrDefault(a => a.Object.FullName == fullName || a.Object.Email == email || a.Object.Address == address
            || a.Object.Occupation == occupation || a.Object.Age == age || a.Object.Sex == sex || a.Object.CivilStatus == civilStatus
            || a.Object.Date == date || a.Object.TypeofCertificate == typeofCertificate || a.Object.Purpose == purpose);
        await client.Child("Table => Certifications").Child(toDeleteCertification.Key).DeleteAsync();
