When a scent has a question mark beside it, it indicates that some authority has placed it in that category, but my experience, as well as other sources, contradict it. (Especially when the same scent appears as all three notes!) However, it is not unusual for a specific scent to fill two adjacent functions, depending on the other oils in the blend.
