"Empty clusters"

Clustering operators such as DBSCAB may produce empty clusters. Despite the fact that DBSCAN can identify all natural clusters in my data I got an extra empty cluster, that makes it impossible to use the "Map Clustering on Labels" operator to map cluster labels to class labels, because I got the following message:

       
The example sets label only contain 4 values while there are existing 5 clusters. Mapping impossible.
Without the empty cluster each cluster could be mapped to one of the classes naturally.

Is it possible to get rid of this annoying emtpy cluster?

Best regards,

Peter
