Hey @jd-foster - I can see that you still have duplicate workflows (two "01" workflow files) so please could you do the following to reset your workflows?

• Manually edit the sandpaper-version.txt file in .github/workflows in your repo, changing the version from 0.18.5 to 0.18.4.
• Commit this change, and run the "04 Maintain: Update Workflow Files" manually with the default options.
• Merge the new raised PR.
