DB’s technicians might be busy.
Still, if I may suggest, you could clarify what you mean with “transfer”. In one year of play, you are the first person who says they are “transferring” their crew. Transferring from what to what? That would help the technicians enormously, I think.
(By the way, in my experience, the most common cause of crew not being able to be discarded/fused is that they are either assigned to a shuttle, or to a ship, or to the Gauntlet. Make sure that Danara isn’t assigned to any ship, even one you aren’t really using often, for instance in the PvP).
