Hummingbird does not appear to be logging the uptime of the website

I have installed Hummingbird and would like to track the up time of the website. After clicking on 'Activate Uptime Monitoring' it goes to a summary page where it shows that the website is up, but it doesn't show any other info. The other fields are all blank. It also does not show the average response time graph.

I have granted access to the website.
