Attached you can find a working example which demonstrates how to export grouping to PDF file. Check it out and compare it to the one on your side to see what is the difference between the two.
I have enabled grouping and I have set the ShowGroupFooter property in the MasterTableView to true
in order to show the footer. I have also added the CommandItem menu and set the ShowExportToPdf property to true in the CommandItemSettings. In the exported file, the columns are properly aligned on my side.
If the issue persists, please consider modifying the attached project to reproduce the issue and open an official Support ticket and send it to us.
