DataPicker error

[JhowDevBR]

Hi guys.
I have an error when selecting the date, as the year is always 0001.
The model looks like this:

[DataType(DataType.Date)]
[DisplayFormat(DataFormatString = "{0:dd/MM/yyyy}", ApplyFormatInEditMode = true)]
public DateOnly DataStart { get; set; }

<material:DatePickerField
Title="Date Start"
AccentColor="{StaticResource Secondary}"
BorderColor="{StaticResource Primary}"
Date="{Binding DataStart , Mode=TwoWay}"
Format="dd/MM/yyyy"
IsEnabled="True"
TitleColor="{StaticResource Primary}" />
