Have you checked the direction of the curves? Flipping one might do the trick.

I checked your file, and your bottom curve has the opposite direction of the others. So it makes sense to flip it.

The Grasshopper Loft component will not automatically adjust closed curve seams, you might want to look at connecting a LoftOptions component to Loft which will allow you to do that, or adjust the seams beforehand with the CurveSeam component.

You can use the _CrvSeam command to manually adjust the start of the curves too.
