Gifs can only have one color that is treated as transparent (since it’s a palette-based 3 channel image, RGB).

Enable transparency = Treats all transparent colors as one transparent color.
Enable transparency + select color = Treats the selected color as the transparent color of the gif.
Detect unchanged pixels = Only cuts parts of the frame where there’s movement.
Detect unchanged pixels + paint transparent = Cuts out parts of the frame that changed and paint in-between pixels with a chroma key that will be treated as transparent.

If “enable transparency” is selected, the "detect unchanged pixels" is ignored.

Right now there's a conflict of both settings and "enable transparency" is not working.
