I cannot switch from BurnUp to Burndown in the Confluence Scrum Template

[Fon Ngu]

I am in the middle of a two week sprint, and I can see the burnup chart, but I don't see any option in Reports to let me switch to the burndown chart. In other words, I see the system defaulting to the burnup chart with no obvious option to activate and see the burndown chart. Any ideas or help to enable me to switch from burnup to burndown and vice versa would be appreciated.

I am using the Jira confluence package.

Welcome to the Atlassian community!

Could you explain what you are seeing when you say "I can see the burnup chart, but I don't see any option in Reports to let me switch to the burndown chart."? 

I ask because I don't see a burnup chart at all, and when I'm in reports, the burndown chart is always there (it's mostly a default view!)
