Thank you for your input; however, we believe that this is not a Documentation Bug.
PlantUML describes the rectangle box by the package name (Person is inside the Model package) and is hence appropriate. Even though Person is a package, but Tag, GroupTag, ModuleTag, and Location are not part of Person package but still under the Model package. Hence, we gave it the Model label.
The caption below states correctly that it is describing a Person. It does not say that the components within the diagram are only those of persons.
Items for the Tester to Verify
:question: Issue response
Team chose [response.Rejected]
[ ] I disagree
Reason for disagreement: [replace this with your explanation]
The class diagram is incorrectly labelled as 'Model' despite it describing a Person.
