Today, I found a dashboard lost the "Add a filter" button. It disappeared, but the created is shown.
The dashboard have one Top N and three Timelion.
After add a Data Table, it appears again.
The dashboard must have a list type component is the rule to show, I guessed.
But the Timelion is a type need the filter.
My kibana version is 5.5.2
Is it a bug in this version, and fixed in other released?
And I suggest to show this button anyways, without the component adjust. I guess nobody want to show a static page as a dashboard.
