Contributors macro does not display creator

Setup:
I have a global template in Confluence. That template contains a Contributors macro.

What I do:
When I go into a Confluence page - press "Add page from template", I get a new page in edit mode with the contributor macro there. I write some more text on the page and press save.

Produced result (imo erroneous):
Then when I view the page no contributors are displayed.

Expected result:
When I view the page, my name should be displayed as contributor.

This affects our OnDemand which seems to have version 6.0-OD-05, but that is not selectable in the Affects version dropdown below.
