Why are unexpected additional owners showing on an entity?

An entity may show additional owners under Owners in the Cortex UI even though they are not listed in the entity's cortex.yaml. This usually happens due to ownership inheritance from a parent domain.

In some cases, you might see:

• The entity's x-cortex-owners lists only one team

• The Cortex UI shows one or more extra teams under Owners

Cause

In most cases, this is because the entity belongs to a Domain whose owners are configured with inheritance.

If a domain uses:

inheritance: APPEND

Then the domain’s owners are automatically added to all child entities, even if those teams/individual owners are not listed in the entity's own x-cortex-owners.

How to Confirm

1. Open the entity in Cortex

2. Open the parent domain

3. Check the domain’s cortex.yaml for x-cortex-owners

4. Look for inheritance: APPEND 

If inheritance is not desired, remove the inheritance field from the domain's owner configuration.
