Ah, yes I did notice that the chapters that didn't have the actual closing tag did end with that forward slash, but I didn't equate it with other self-closing tags I know of. Probably simply because of the other that DID have the separate tag. I see these simply when using Calibre editor, and I see both options in the same story when updating. New story only shows the self-closing. A little strange, but as long as no problem I won't wonder anymore
