You must be using a model with PNG textures, PNG have native transparency support so you don't need that extra alpha layer. If you want to get alpha layer out of PNG then first save it as DDS and copy Alpha layer from that then once again save that PNG as TGA and paste your copied Alpha layer in that.
The reason you use TGA is because it's supported in Unreal and both PNG and TGA are lossless formats while DDS is a lossy format so it should only be used for getting that alpha layer.
