Unlocking Stella and other new characters

[OptimusPrimeTime]

Hi! I am on level 240 and I see Stella in my barracks but I cannot select her. She is grey. The same for my other new characters. I am not sure why. Any insight is very much appreciated! Thank you. :-)

@angela-hershey They are unlocked in the mission portals. The two Stellas in the easy portal (one in the middle) and the Blues in the medium portal (top left). The mission that has them as an award will be tinted yellow.
