2 rail surface has a bump, any ideas on how to smooth?

I have created a few surfaces using the 2 rail command. I have a few in my file for examples of good surfaces but one set of curves is creating a bad surface. I put the bad surface in red. Any ideas on how to get that ugly bump out of there? Thank you for any help.

With those curves, I think you’ll get a result closer to what you want using NetworkSrf.
