Image Fill not reflecting changes after reaching value 0

Hi Guys,
Ive been messing around with the new GUI to make our prefabs and GUI lib for the designers at our studio. It looks like i came across a bug while paring a slider to change image fill value. The image updates very nicely until it reaches 0. After reaching 0 it does not update the fill on the scene view. But hierarchy shows the value changing flawlessly. ive just written a simple public function to do the same

public void OnImageSliderChange(float value)
{
ForeGroundImage.fillAmount = value;
}

and this is assigned to theSliders OnValueChange Event in the inspector.

Is this a known bug or is it something that i am doing wrong out here ?
Regards
