Multiple NumericUpDown controls not displaying correctly

[corvinsz]

Bug explanation

When having multiple NumericUpDown controls on a page only the last control actually displays the content of the increase and decrease button correctly.

I uploaded a project showcasing the bug: https://github.com/corvinsz/MDIXNumericUpDownBug

Here is my code:

<Grid>
    <StackPanel HorizontalAlignment="Center" VerticalAlignment="Center">
        <materialDesign:NumericUpDown />
        <materialDesign:NumericUpDown />
        <materialDesign:NumericUpDown />
    </StackPanel>
</Grid>

Result:

Am I perhaps doing something wrong?
