Surface by Loft is forming to all of the guide curves except for one

What’s up Dynamo experts! I finally took off my practical Dynamo hat and threw it into the complex surfaces ring. So I need some help figuring out why my surface by loft script is not forming correctly, but my surface by patch is. See image -

I would use the surface by patch going forward, but the surface by loft is forming to my curves like I need them to, and the surface by patch isn’t. see image -

My question to all of you is, how do I get the surface to follow the guide curve in the following image? I tried almost everything in the Dynamo toolbox with no luck.

. Here is the Dynamo graph I am using. Surface by Loft Script.dyn (514.1 KB)
