Future star evo unable to do

Hi, I picked Nwaneri and done the first evolution on him to 84 - I'm not sure which evolution it was but I think it may have been the rapid/block evo that was earned through this same objectives section  that I applied to Nwaneri. He's now gone green in colour and I can't do the next evo upgrade for future stars. 

I'm not sure if this is a bug or a mistake on my part, if it's a mistake then I was completely unaware that adding this evo would change his evo category and subsequently stop the future star evo. 

Please can you change him back and remove any playstyles that have caused this so that I can continue the future starts evo as this is all I want to complete. 

Thank you.
