How to fix this error?

The selected link has no definition.
Possible causes:
1. The source node or target node of the link is not an entity type,
but a data model. In this case, the link is simply a graphical
compression of the relationships involved and has not separate
definition. To display the entity types and their relationships,
first select the data model and select Edit -> Expand.
2. The link is a relationship where source entity type and target
entity type are identical.
