Loft problem

Hello, guys! I have a problem with a definition. Do you know why the proporties of Loft command are lost such as in image?

All I want is a loft between these lines, but unfortunately is not running in good condition in every pairs of lines. (47.1 KB)

Thank you in advance for your help!

In your picture the result looks to be good. In my case, when I bake the result, this one is such as in the picture below.

It`s a Loft between the edges but in some cases, the surfaces are overlapping.
