Hi,
Although I see similar questions have been asked by different users before, but still I'm not able to find a satisfactory answer and I'm not sure if it's a bug specific to workspace analysis?
If I just want to see an overall view of avg.time spent on site, I see 'infinity' but if I break it down by months or some other dimension then I can the values being populated. However, it's also not the case, when we apply segment. Let me share with few screengrabs.

Can you anyone help me here?
Thanks!
