Blender fbx "armature" bone

Hey all,
I want to fix animations from fbx files(rigged characters) but upon export, blender adds an extra bone called “armature” on top of my rig hierarchy and unity cant read the animations.
I searched for a solution and i found a small hack with the export python file in blender addons ,hashtaging several lines but it doesnt work.

Has anyone solved this issue ?
Any help is greatly appreciated!

Thanks
