It will only show up if you do a loft with 3 or more profiles. A loft between just 2 profile curves won't have the option for making a closed surface.

I think your original problem came about from something like gluing together 2 projected curves at some spot other than the natural endpoints, like at a trimmed spot or at a spot where the projection ran off the silhouette. Those spots will be accurate enough to be joined but the curve end tangents at such areas may be slightly off because projection curves are the result of a fitting process. You would need to true up the curve's end tangents in such cases by editing the end and first interior points to ensure they are totally smooth to each other and that would make for better filleting.
