Repeat Button Style Setter/Triggers Doesn't Work

Question

I'm using the Extended WPF Toolkit's IntegerUpDown control.

I was able to stylize the arrow buttons in a previous question.

Before

After

I've run into some additional style problems:

I'm using PresentationFramework.Aero and Aero2.

<!-- RepeatButton Style -->
<Style x:Key="{x:Static theme:ResourceKeys.SpinnerButtonStyleKey}" TargetType="RepeatButton">                 
    <Style.Triggers>
        <Trigger Property="IsEnabled" Value="True">
            <Setter Property="Background" Value="Transparent" />
            <Setter Property="BorderBrush" Value="Transparent" />               
        </Trigger>

        <Trigger Property="IsEnabled" Value="False">
            <Setter Property="Background" Value="Transparent"/>
            <Setter Property="BorderBrush" Value="Transparent" />
        </Trigger>

        <Trigger Property="IsMouseOver" Value="True">
            <Setter Property="Background" Value="DarkBlue"/>
            <Setter Property="BorderBrush" Value="Transparent" />
        </Trigger>

    </Style.Triggers>
</Style>

The IsEnabled False Trigger will not override the Disabled Background or Border Color. It always stays White, I need it Transparent. However I can override the Opacity and BorderThickness. (Windows 10):

Cannot change the IsMouseOver Background Color, always Light Blue. (Windows 10):

Windows 7 always displays a White Border, even if BorderThickeness is 0 and Color is Transparent or {x:Null}:

I think it is being overriden by a Control Template, but IntergerUpDown doesn't have a RepeatButton Style within the Control Template and I've had trouble trying to add one. I had to create the Style outside.

some properties won't work when you set via Style setters. This is because of Dependency Property Value Precedence. Try changing the values in ControlTemplate triggers.
