Yeah, Rawzombie - look at your bones. At least they’re facing in the right direction. LOL Look at the Blender bones they’re all facing in different directions. Or, more accurately, they’re facing in the same direction - only clockwise. LOL Try animating that! It’s a pain to be sure but at least the original content was created in Maya and so will work better. That having been said, unless you have a dire need to use Epic’s animations you can still create your own skeleton and that will usually work just fine. Of course if you’re trying to create content for the marketplace you have no choice but to work with that skeleton.
