In the "Manage panels" dialog in the Overview tab, if you filter on "total", "bar", "donut", or "line", nothing is shown even though there should be some selections.

Another issue is if you click the button but not the text in the button, it will not register.  Oddly enough, this problem does not occur in the similar "Manage columns" dialog in the Traffic flows tab.

1. Go to Observe > Network Traffic".
2. Select "Overview" tab.
3. Click "Show advanced options".
4. Click "Manage panels".  The dialog comes up.
5. Click the "donut" button.  No panels are shown.
6. The same is true for the "total", "bar", and "line" buttons.

Also, see Description above on the button problem.

No panels are shown.

All panels with "donut" in the panel text should appear.
