When using the Worklist WebPart and control - 'Filter on Activity' needs the SystemName as input, using the DisplayName as in the webpart, or the control does not work.
If the Filter on Activity does not have the SystemName as input, the Worklist will return empty.
This is a known issue.
As a workaround please do the following:
1. Filter using the SystemName (It might be hard to find the systemname).
2. Instead of using Activity filter one can use the Event Name as the filter together with the Actvity DisplayName.
