Cause:
=========
The ownership, "ownerPath",  was wrong for all of the poperties on one of the rules.  A concept was moved using an "unsupported" mechanism for example drag and drop from Navigator, using file system, etc.  The proper way to move these entities is the Refactor-&gtMove option.

Resolution:
=========
Correct the ownerPath be either:
1). Drop and recreated the concept which has this problem.

2). Open the declared concept with text editor, set OwnerPath with correct value.

e.g.  &ltproperties name="nombreOdN" ownerProjectName="ODN" ownerPath="/Concepts/OdN/ODN"/>
