Risks are shown in High, medium but not shown when 'All' is selected'

Hello Experts,

Please can you help me here?

1. When i try to run the risk analysis at high, medium, low level. The SOD violations are shown.

2. But when i select the risk level as 'all'. it does not shows anything for the same search criteria.

3. When i remove risk level from the analysis criteria all kinds of risks are show ' High, medium and low'

Thanks,

Ram
