Hi everyone!
I would like to thank straight away for any help I will get.
I have a problem with my animations. I have uploaded my basic character with the rig attached to unreal engine yesterday. Straight away i saw that there is a problem with my animations. Every part of the Rig seems to working be fine except for the hands. They are set to be in idle position or aiming down position in blender on all the animations yet in unreal engine they are in a strange " I’m a plane" position 
I am attaching a screenshot below.
I know it is probably something simple although I didn’t manage to find an answer anywhere.
I tested the rig in unity3D and the animations are working as they should…
