I think you are misunderstanding the meaning of rdfs:range (a very common mistake) Per definition, rdfs:range is an instance of rdf:Property <https://www.w3.org/TR/rdf-schema/#ch_property> that is used to state that the values of a property are instances of one or more classes.
So, rdfs:range is not supposed to be used to restrict the "kind" of an object, but to infer it. If you want restrictions, try something like SPIN.
