would not be surprised if it was that koffi with the heartbreak of losing fally ferre koffi tried to see which of them could handle continuity of the group and was all over the place,even when the dream was complete only fally was automatically getting the duet even if it could be at expense of somebody,the rest of the time koffi could wake up and feel like bouro,then soleil the day after,i think thats probably why for example he allowed soleil only on sexy pop to make him feel like he also got a duet
gabbana aswell when he was the first to join was promised a duet which did not happen
