slate SBorder Brush not working as intended

[envenger]

I tried to make make a SBorder but I got some problem with it.
The border appears but its sides are not being scale with relative to any content present inside it.

Here is my code

     + SOverlay::Slot()
    .HAlign(HAlign_Right)
    .VAlign(VAlign_Top)
    
    SNew(SBorder)
    .BorderImage(&BallHUD->ScoreBoardBrush)
    .Padding(FMargin(0, 5, 5, 0))
    .Content()
    
    SNew(SBox)
    .Padding(FMargin(2, 2, 2, 2))
    
    SNew(STextBlock)
    .Text(FText::FromString("9999"))
    ]
    ]
    ]
     

This is my Brush

And this is how it looks like
