Lable Outline not working for System Font?

Hey,

I’m trying to use enableOutline for System font but somehow it only works for ttf labels, even though it says it should also work with system fonts in the code comments:

auto text_level_number = Label::create("TEST", "Arial Black", 50);
text_level_number->enableBold();
text_level_number->enableGlow(Color4B::BLACK);
text_level_number->enableOutline(Color4B::BLACK, 12);

The same goes for enableBold
and not sure what glow shoud do because when the text is white itself it doesn’t really do anything.
