Custom progress bar (White outline)

Hello !

I have been creating my custom progress bars for my project, this is the bar.

and this is the desired final result.

This is its current alpha channel

Some how when i bind the progress bar to the image, this is the result i get …

Notice the White Outlines, its not at all what i want.
What am i doing wrong ? and how can i solve this ?

Thanks!

Ok, found the solution.
If you come by this problem you only need to adjust the chroma key in the image settings to the desired results.
