Incorrect Color

I have installed WLED onto a Amica nodemcu and my lights are working except for one item. When I select certain colors from the color wheel I don’t always get the correct color. If I select red the LED turn green, when I select green I get red. But if I select blue I get blue.

Could this be a WLED issue or an issue with my Rextin WS2811 Pixels ?

Go to main menu
Select Config
Select LED Preferences
(Scroll down about halfway down list)
Select Color Order
(It’s a drop down menu - change order of red&green)
