Boleto.Net Component Generating Wrong Code

I'm working with the boleto.net library, I'm generating boletins from the brazilian bank and the following problem is occurring.

I am generating the right ticket but the ticket bar code is coming with the end, where would be the wrong ticket area + VALUE TICKET area.

Below code returned from property BoletoBancario.Boleto.CodigoBarra.Codigo 00196.88472 32677.473001 00000.085183 1 550000000002

Below code returned from the BoletoBancario.Boleto.CodigoBarra.LinhaDigitavelFormatada property 00190.00009 02688.473269 77473.0000000085187 1 67830000055000

If you analyze the above codes, if we take the final stretch ( 550000000002 ) of the first and insert the end of the second code ( 67830000055000 ), the ticket is generated correctly. / p>

                };

boleto_bancario.Boleto.Valida();

boleto_bancario.MontaHtmlEmbedded();

Is this the data that is filled in, something wrong or missing?
