I'm following a youtube tutorial to practice my skills at solidworks. I'm trying to surface loft between two profiles using guide curves. I have a total of 4 guide curves but it won't let me use two of them, it only works with one or the other. I really need both. Can anyone help with this issue?

I've attached an image showing which two guide curves are the problem, I've also attached my solidworks file.

Solidworks: Panton chair - YouTube < This is the tutorial I'm following but it doesn't help with my problem. My email is oliver.j.sunderland@student.shu.ac.uk please get in touch if you think you can help.
