POWL - Active Query Results Not Refreshing

Within SAP TM when I go to a Worklist page such as 'Overview Planning' I see that there are active queries with results to be displayed. When I click on the active query it states that it is 'refreshing', come back with a number or results, HOWEVER nothing is displayed in the result table. The only way I have been able to get the results to display is to change the 'default' active query on page load, this will allow the results to be displayed.

Addtionally there does not appear to be an authorizations missing (su53).

Any help would be greatly appreciated.

Thanks
