I followed these instructions carefully: https://confluence.atlassian.com/conf65/decisions-blueprint-939700993.html
but the after Save I expect "Once you save your first decision page, Confluence will create a decision register page for the space you're in, and add a shortcut to it in the space's sidebar." The decision page was created but not the register page. [This just continues to frustration and seemingly bad documents/non working application as I try to get to work "Build a Project Portfolio Dashboard". https://www.tacticalprojectmanagement.com/confluence-tutorial-project-portfolio-dashboard/#comment-10511. This too fails as the "Page Properties Report Macro" always shows "no content". I've retried carefully with the same results.
