It is with me. Not sure about anyone else. Saddens me that I paid over 50$ on characters that I am forced to use in 4.7 to get any kind of compatibility. I would LOVE for these to be updated as I use the Dark Military models and still nothing. Even after that whole “Follow each step in the tutorials” bit and then even trying my own retargetting, I get some chickenwing looking bits.
The only suggestion I would have, if you have Maya, is to export animations and then export the .fbx you purchased, try to manually set the animations that way, then re-import to Unreal. Worth a shot until these marketplace fellas improve their characters.
