unmitigated SoD conflicts for the user

Hello Everyone,

I am working on SoD conflicts analysis and remediation on GRC 5.3. I have come across a very weird situation. I got two users with unmitigated SoD conflicts.When I pulled the RAR report on Org. Level, I found two org. values(Org. rule) as "NA".I cannot see any role modification as well.Can anyone tell why the unmitigated SoD conflicts is coming for the users?

1. I have checked the validity for the Mitigation control

2. I have checked whether mitigation is assigned to the risk or not

3. I have checked the role modification as well
