I think this is a known issue already under investigation - I’ll try to find the issue
Dashboard: Event in list but not shown on timeline
Update:
As it turns out, since the dashboard/console is not open source, there is also no dedicated public place to file an issue (or keep track of known issues).
It might be something to think about tho’ or if there is one, it would be good if the link was posted in the respective threads, to tie up loose ends - @jeiden
