Why does CsvHelper raise an exception reading a string as it would be empty, when it’s not?

I have a TXT file to parse and I’m using the CsvHelper package to do so. The content of the file is:

 A; B; C; D; E; F; G; H
a;b;;2021-05-06;e;11:00;3;9

Note there’re spaces on the header line, before the column names ( A, B, etc.).

I’m using the following class to parse the CSV:

public class MyClass
{
    [Name(" A")]
    public string a { get; set; }

    [Name(" B")]
    public string b { get; set; }

    [Name(" C")]
    public string c { get; set; }

    [Name(" D")]
    public DateTime d { get; set; }

    [Name(" E")]
    public string e { get; set; }

    [Name(" F")]
    public TimeSpan f { get; set; }

    [Name(" G")]
    public string g { get; set; }

    [Name(" H")]
    public string h { get; set; }
}

and the following logic for the deserialization:

var reader = new CsvReader(myStreamReader, new CsvConfiguration(CultureInfo.InvariantCulture)
                {
                    Delimiter = ";",
                    MissingFieldFound = null
                });

reader.GetRecords<MyClass>().ToList();

My problem is that I get the following error at runtime:

It seems to say it isn’t able to understand the 2021-05-06 date, but not because the format is not valid, instead the error shows that Text: '', while I’d expect Text: '2021-05-06'. I tried using the [Format("yyyy-MM-dd")] attribute like said here, but without success (maybe because it’s only for writing, not reading).
