It happens to me on Xbox 1 as well. Ive done about 15 now and the game I littery finished is the only game it actually registered. Granted I killed the enemy and they were revived by a squadmate. I immediately did the takedown while they were still on the ground and it went through as a kill. It might be just because they were prone.
the one takedown I haven't done yet is prone, thanks for the reply I will try this one and hopefully it works
I finally did it, I tried every knife but it looks like its the first knife, The rib opener and the subject was standing up but thanks to all you guys for answering Thank you
