sweep1 multiple cross section issue

Im trying to creat a sweep1 that uses a rail and has 4 cross sections. IIm running into an issue though. I think the issue is that grasshopper is reading them as different curves. The first 2 section curves were generated eariler in the grasshopper script and when connect them to the note pad thing I see in the top right corner (0;0;0) for the last two curves when I do the same thing I see (0;0;0;0;0). Any thoughts or suggestions?
