Configure PDF Headers and Footers ,but it didn't work

[刘平平]

I refered documentation in the link "https://support.atlassian.com/confluence-cloud/docs/customize-exports-to-pdf/#Setting-a-global-PDF-layout-" to configure PDF Headers and Footers, but it didn't work.

1. As below, it's my configuration of PDF Space Export Header.

2. The configured information was not display in the PDF 

I am looking forward to your reply.

Thanks
