Export Selected Objects doesn't work.

So I designed something in Lumberyard, and I was looking to see if there was an option to export. Turns out, in 1.12.0.1 going to Game > Export Selected Objects, allows me to export an .obj or a .fbx. I selected both, and nothing happens, it exports the file, but when you import it into Maya, 3DS max, Unity, etc. it shows absolutely nothing. So it’s basically like it’s not even exporting anything at all and just making a file. This is really annoying, can anyone help me out? Because there is a section of my level I would like as an object, but can’t use because of this.
