Thank you for your post.
Is the saving of a PDF being performed by a script or manually? If manually, make sure the orientation is set to portrait in Print Setup prior to tapping PDF. If this is being performed by a script, then revisit the Print Setup script and make sure the orientation is set to portrait. If it shows portrait, then switch to landscape, switch back to portrait, and then save.
If you continue to have difficulty, please provide all of the Print Setup settings and I'll try to replicate the problem here.
