Herorotation addon

I love this addon for my alts for a crutch to play until I get the rotation. However, some of my toons show the icon WITH the corresponding keybind although some toons don’t show the keybind.

If you use this addon, can you tell me what setting I’m missing to see the keybind? Thanks

I actually code my own rotation addons. My spell icon for barbed shot is color coded so I can tell how many stacks of frenzy my pet has. I used GIMP to make the color alterations. Red = 0. Yellow = 1. Green = 2. Cyan = 3.
