Nwaneri Evolution Future Stars Problem

 Hello, Hope you can help me with this problem. I was evolving Nwaneri with different evolutions earned from the objectives and from the weak foot + evolution; my Nwaneri became a simple evolution, not a future star evolution. Now I can't put him in any other evo for the future star event. Please help me; I do 'n't want to lose my progress, and I don't want to be left out for this event. I really hope you can help me solve this. Best regards, Andrei
