Looks like there are some problems with the seam generation in Enblend that can lead to some of the problems you are seeing. Try turning off seam optimisation to see if that helps ( http://enblend.sourceforge.net/enblend.doc/enblend_4.2.xhtml/enblend.html#sec%3Amask-generation-options). To isolate the problem, you can generate the remapped images in Hugin and save them, then run Enblend separately with different options. You can also run different image blenders on the remapped images to see what works.
You also want to try generating HDR (e.g. EXR format) files from your exposure stacks first before stitching them in Hugin. I've used this method previously with success. Daniel.
