Hello Keith,
Some of them are just suggestions based on the username, file name, current date, and so on.
So you cannot delete them, they are built-in!
But if you have some custom headers and footers already found in the workbook, you will see them in the drop-down list.
If you want to delete all the custom headers and footer from your workbook at once, you can do it as follows:
- Go to File >> Info >> Check for Issues >> Inspect Document.
- From the Document Inspector dialog box, deselect all checkboxes except Headers and Footers checkbox.
- If the Document Inspector found some headers or footers in the workbook, you will see a button to remove them all.
Hope that helps!
Haytham
