> There are two issues over here.
> *1st issue:*
> This seems to be a functional bug. As it seems from the attached screenshot that even after API call was completed content was not rendered.
> *2nd issue:*
> There seems to be a performance issue. UI asks for all tasks fields instead of only ones that are needed making api call really expensive. Expected behavior is that only status should be asked for and when user clicks on a task then  log for that task should be requested.
