There is a minPropertyCount limit in the statistics to reduce general
purpose templates and it is set to '2'. Starbox_begin template has only one
label property and that is why it is miscalculated.
There must be one wrong instance with two properties defined that's why you
see only one.

This is a known problem but the framework doesn't handle this type of
information.
Whenever there is a mapping the framework expects a class definition and it
either assigns it in the article resource or in a new "intermediate"
resource ( in the case of multiple defined mappings )

To solve this I think we should add a "noMapToClass" property in the
templateMapping and whenever the framework reads that definition it just
adds the mapping output directly to the main resource without rdf:type info
Would you like to help in this regard? We could of course help you and
