Anyone with experience growing Aji mango?

In the first picture is one of my aji mango peppers and that's the color I expected. In the second picture is another plant but they seem to be staying yellow. The pepper in the first picture went from green straight to orange unlike my habaneros which went green, yellow, then orange. In the last picture, the pepper that is ripening appears like it may be going orange, maybe yellow, but it's on the same plant as the yellow peppers. Is this normal or could I have gotten seeds of a different type of aji pepper?
