SDN5: Found more than one matching @RelationshipEntity for (14762)-[CONTAINS]->(14781) but cannot tell which one to use

Question

I have created two different Spring Data Neo4j 5 @RelationshipEntity with the same type:

@RelationshipEntity(type = "CONTAINS")
public class CharacteristicRelationship {

    @Id
    @GeneratedValue
    private Long id;

    @StartNode
    private CharacteristicGroup characteristicGroup;

    @EndNode
    private Characteristic characteristic;

}

@RelationshipEntity(type = "CONTAINS")
public class DecisionGroupRelationship {

    @Id
    @GeneratedValue
    private Long id;

    @StartNode
    private Decision decision;

    @EndNode
    private DecisionGroup childGroup;

}

everything is working fine and I'm successfully able to pass all my tests but right now I continuously getting the following errors in the console:

2018-04-29 15:36:52.387 ERROR 7664 --- [           main] org.neo4j.ogm.context.GraphEntityMapper  : Found more than one matching @RelationshipEntity for (14762)-[CONTAINS]->(14781) but cannot tell which one to use
2018-04-29 15:36:52.390 ERROR 7664 --- [           main] org.neo4j.ogm.context.GraphEntityMapper  : Found more than one matching @RelationshipEntity for (14762)-[CONTAINS]->(14779) but cannot tell which one to use
2018-04-29 15:36:52.391 ERROR 7664 --- [           main] org.neo4j.ogm.context.GraphEntityMapper  : Found more than one matching @RelationshipEntity for (14762)-[CONTAINS]->(14774) but cannot tell which one to use

What am I doing wrong and how to fix it ? Does it allowed to have different @RelationshipEntity with the same types ?

at org.neo4j.ogm.context.GraphEntityMapper.getRelationshipEntity(Edge) I can see the following code:

} else {
    // almost definitely a user bug
    logger.error("Found more than one matching @RelationshipEntity for {} but cannot tell which one to use",
    edge.toString());
 }

that just prints the error log and that's it. It is really hard to understand from this - it is a bug or no and how to deal with it.

The classes:
