Hi Front!
There is a component in Grasshopper called "Flip", it flips the normals of a surface and there is the option to add a reference surface as a guide. What you could try is to insert a reference surface that you know has the right orientation as that guide and see if this works. If not, post a screenshot of your grasshopper definition and I'll have a look and see what we can do.
Cheers!
