Bug: how remove wrongly created views?

[Tcharl]

Hi,
Facing an issue when trying to delete/modify an existing capella diagram with 6.1.0 Teams.

!ENTRY fr.obeo.dsl.viewpoint.collab 2 0 2024-06-28 16:06:36.515
!MESSAGE The element {eClass: notation::Edge} 'Edge@OID383181' is referencing an unknown element through the feature 'styles'. It is recommended to delete the element.

I guess that a viewpoint views has been created but unlinked to its semantic element. Still, I'm not able to do anything anymore with this diagram. Any fix?
