Querying relationship tables between regular node and RDF.Resource tables without node labels gives binding error.

I have an RDFGraph UniKG. It has a Resource with iri: "http://kuzu.io/rdf-ex#Adam". I add a new node table Students and a new relationship table between Students and UniKG_r (the resource node table). Then I get the following error:

kuzu> CREATE NODE TABLE Students(name STRING, primary key (name));
------------------------------------------
| result                                 |
------------------------------------------
| Node table: Students has been created. |

kuzu> CREATE (s:Students {name: "Adam"});
kuzu> CREATE REL TABLE SameStudent(FROM Students TO UniKG_r);
--------------------------------------------
| result                                   |
--------------------------------------------
| Rel table: SameStudent has been created. |
--------------------------------------------
kuzu> MATCH (a:Students {name: "Adam"}), (b:UniKG_r {iri: "http://kuzu.io/rdf-ex#Adam"})
..> CREATE (a)-[:SameStudent]->(b);
-
(0 tuples)
kuzu> MATCH ()-[s:SameStudent]->() RETURN *;
Error: Binder exception: Query node  violates schema. Expected labels are Students.

In the last query, if I instead query as follows it works:

kuzu> MATCH (a:Students)-[s:SameStudent]->(b) RETURN *;
----------------------------------------------------------------------------------------------------------------------------------------------------------
| a                                        | b                                                            | s                                            |
----------------------------------------------------------------------------------------------------------------------------------------------------------
| {_ID: 5:1, _LABEL: Students, name: Adam} | {_ID: 1:5, _LABEL: UniKG_r, iri: http://kuzu.io/rdf-ex#Adam} | (5:1)-{_LABEL: SameStudent, _ID: 6:0}->(1:5) |
