Setting color transparency to 0% is not working

This is about a bug in the lottie creator.

Like mentioned, when editing the color in a keyframe i was trying to set the transparency to 0%.

What I expected to happen: Transparency is set to 0%.
What actually happened: Transparency is set to 100%. (both when using the slider and when typing the 0)
