Biggert, As falcon says, the problem that you have is that you have a multi-gon (don't know what else to call it) selected. Notice that you have closed portions of your duplicated polygons (See orange arrows). Deslect these edges and you should be able to loft with no removal of the endcaps. As I tend to loft alot, this is a common problem for me. Don't know why it even let you, though. Most of the time I get an error when I try to do that. Ken
