Hugin and enblend are using libtiff (via vigra) to write the images. And they write tiff files always with an alpha channel. So the shown image was not touched by Hugin at the end. Another software has removed the alpha channel without correctly updating the header. This is nothing which can be fixed at Hugins end.
