OK, I see the problem. Two solutions:

 1. The simplest is to add an empty ERT box to the first item. This will
    prevent LyX from collapsing the empty element and adds nothing to
    the output.
 2. Local Layout:

        Format 66
        Style Enumerate
        KeepEmpty 1
        End

The "KeepEmpty" layout tag instructs LyX not to delete empty lines.
