Blender animation is messed up after import in Ue4?

Hey i got an very simple animation but after importing the fbx file into Ue4 its a bit messed up. I tried a few settings but nothing helped so far. I created the animation with blender 2.77. Does anyone know the right settings for exporting the blender file properly?

Well I know a tutorial that might be of your help
