i was referring to the skeleton, Art Jointer mover for the mannequin was off, the left arm upper wist is in the wrong position same with the arm and feet .
This is the same result i got when using the Art template skeleton-joint mover with the mannequin - https://www…com/watch?v=O4LNvsFyuLM&list=PLZlv_N0_O1ga0IoRrpI4xkX4qmCrhGu56&index=11
Not being rude or anything was just letting you know, as i made the template for you identical with ue4s engine version as your busy with projects. Was showing in my video that the skeleton is now identical to the engines mannequin after fixing it, so even with custom models due to the skeleton being identical with no issues you can now replace it with UE4 mannequin Skeleton when importing into unreal, so it can share animations without any re-targeting or setting anything in engine for the skeleton, as long the skin weights are correct and your model is in the identical A-Pose 
so the hand poses shouldn’t of been in art hmm, well there in 4.14 Version to let you know :D, thats also good to know the hand poses will work once iv made my own.
