Bar border not working

[ObsidianChickenz]

Config:

# Bar
screens = [
    Screen(
        top=bar.Bar(
            [
                widget.GroupBox(),
                widget.Prompt(),
                widget.Chord(
                    chords_colors={
                        'launch': ("#0000ff", "#ffffff"),
                    },
                    name_transform=lambda name: name.upper(),
                ),
                widget.Clock(format='%Y-%m-%d %a %I:%M %p'),
                widget.Systray(),
            ],
            24,
            background = "#282a36",
            border_color = "#565f89",
            border_width = [0, 0, 2, 0]
        ),
    ),
]

I want to add a 2px border to the bottom of my bar but it's not appearing. Am I doing something wrong? I can provide other files if needed, but this is the only bar.

This feature is so far unreleased, so is only available when running Qtile from source. Are you doing that, or are you running from a release version? If you're on a release, it won't be long until a new release is out!

I'm on the most recent release on Arch, so it must be unavailable. Thanks for the quick reply!
