Text inside badge doesn't centralize

I have this code

<Grid      
    xmlns="http://xamarin.com/schemas/2014/forms"      
    xmlns:local="clr-namespace:Operacional"     
    xmlns:x="http://schemas.microsoft.com/winfx/2009/xaml"   
    x:Class="Operacional.BadgeView" 
        Padding="5"
        Margin="1"
        HeightRequest="16"     
        WidthRequest="32">

    <local:CircleView x:Name="BadgeCircle" 
                      HeightRequest="16" 
                      WidthRequest="32" 
                      CornerRadius="16" 
                      VerticalOptions="Start" 
                      HorizontalOptions="Start" />

    <Label x:Name="BadgeLabel" 
           TextColor="White" 
           VerticalOptions="Start" 
           HorizontalOptions="Start" 
           VerticalTextAlignment="Center" 
           HorizontalTextAlignment="Center" 
           FontSize="10"/>
</Grid>

see that VerticalTextAlignment and HorizontalTextAlignment are center, but when running the app, the text are in start of badge and not center.
