I can change the two options in
Entitiy Properties->Subtypes->Entitiy and subtypes generation preset
and the change has some kind of effect. But when I save and reopen the model the changes are lost. And during the next engineering some strange things happen.
Is this a bug in my model or a bug in the modeler?
it's not a property, it's preset functionality - Entity Inheritance
Thanks. Was not intuitive for me.
