Operations Monitor - No activity is associated with your current selections

[JustinDallas]

Hello Folks,

I'm on QS Apr 2020 Patch #2.  When I go to my Operations Monitor dashboard, for some of the sheets, they are filled with the text "No activity is associated with your current selections"

I know people are using the application, so their should be data.

What I've tried.

1. I've tried restoring the Operations Monitor from "C:\ProgramData\Qlik\Sense\Repository\DefaultApps" to no avail.

I'm unsure of what to do next.  I use this particular dashboard to judge usage and hardware capacity limits.
