Tempo report is throwing error which says " No Enum constanct.."

Hi,
Requirement is : convert Portal Task report to Tempo Task Report and add date filter with 4 options (Last 7 days, Last 30 days, Last 60 days and All).
e.g.If i select Last 7 Days, it should display tasks assinged in last 7 days.
When I tried '>=' operator in filters, tempo report is throwing error which says " No Enum constanct..". So can you please guide me to resolve the issue.

Thanks in Advance.
