Why doesn’t the UICorner work on the BarFill?
Both UICorners’ CornerRadius is set to 1,0 [Full circle]

I wouldnt use corners for this, instead try swapping out your barbackground with a canvas.
Maybe it’s bugged? I tried the same thing and it looks fine.
It’s been days already. Did you find a fix?
Have you checked if the BarFill frame has any negative size? UICorner
doesn’t support GuiObjects with negative size, for example {0, -100, 0, 100}
.
It also is not recommended to use negative size either way, according to a Roblox staff reply in this post: UICorner Breaks With Negative GuiObject Size
you’re using uicorner.scale.
you’d want to use offset
