Error While running DB consistency Check

Hi everyone. I ran DB consistency check in my lab environment and I am getting only one error "Missing Unique Key for XObjectkey" and When I open this error, in the test result, there is a limited error message as below:

Missing unique key for XObjectkey.
QAMSecurityEntry XObjectKey

I am running lab environment with Identity Manager 8.0.2 and has very limited data and all settings are mostly default. I was expecting zero errors, does anyone faced this issue?

Best regards,
