 Make sure that you provide the ID of the customized profile in `--profile` option instead of the ID of the original profile.
-If you created the tailoring file using SCAP Workbench, you were prompted to choose the ID of the customized profile. You can display the ID of the customized profile by running `oscap info <your_tailoring_file>`. By default, the ID of the customized profile ends with `_customized` suffix.
