None of the logical destination names is available

Question: In the system list, none of the logical destination names is available. What can I do?

Verify that

Portal aliases available on the search drop down list while logical destinations are not
Check that all the logical destinations are well defined
If one of the destinations is not defined well, you might not get any system at all

Solution
Delete the logical destination that is not well defined, alternatively, define it well.

Note
Do not "Save" after "Delete", otherwise it will not be deleted.
