We have confirmed that the current behavior—an error occurring when loading task lists in the "Focus View" if related entities are used twice within a view and two "link-entity" elements are configured in FetchXML—is the default operation.

This issue occurs because the same related entity (link-entity) is used twice with identical relationships in both the "to" and "from" attributes.

However, in Personal Views or customized system views, there are many cases where setting multiple "link-entity" elements in FetchXML is necessary.

We believe that improving this behavior would enhance user convenience and contribute to further increases in operational efficiency.
