Why is "Patch" Surface Tilted in the U, V axes?

I created surfaces using the Patch command over sets of manually generated point cloud points (about 20 points each). Most surfaces have the U,V directions aligned with X, Y axes, except for one that is diagonally tilted. Does anyone know why that is and how to straighten them?

Hello - Patch, unless it is given a specific starting surface, makes its own starting surface and that has no particular orientation in the world, it depends entirely on the distribution of the inputs.’
