Failed to get 10th anniversary achievement "The Moebius Factor"

Hello there is an error in the mission “The Moebius factor” does not skip the achievement:

"Saviors by contract
Complete the mission “The Moebius Factor” training only VCE, Evameds and Mercenaries at the Normal level. "

I have fulfilled it to the letter and even with only 4 mercenaries and 2 evameds and a VCE, and the achievement does not come out. It would be nice if they fixed it please.
