Contextual Scope Failure in MBOM/Workplan with Multiple Instances

We have multiple instances in the MBOM and Workplan, and when we try to apply Contextual Scope, we receive a “Contextual Scope creation Failed” error.

Has anyone encountered this issue before, particularly in the 3DEXPERIENCE Public Cloud environment? If so, could you please share the root cause and any workaround or resolution you used?

Any guidance would be appreciated.
