Archetype tags sometimes missing

[simonbrowndotje]

Expected

Both software systems in the following example should have Default Tag.

workspace {

    model {
        archetypes {
            softwareSystem {
                tag "Default Tag"
            }
        }
        
        a = softwareSystem "A" "Description" "Tag A"
        b = softwareSystem "B" {
            tag "Tag B"
        }
    }

}
