FFTB: "The profile has an active tree, not updating"

What does the light green category mean? Does it mean I should just accept the tree, assuming only one is remaining for the item? How is this different from the dark green items (“identical” ones)?

Thanks!

You will see the dark green color for fully disambiguated items in FFTB when you first update, and then whenever you revisit that updated profile later, those fully disambiguated items will appear in light green instead.
