Those are LSA's with DoNotAge bit set.  AFAIK there is no way to clear those entries without doing clear ip ospf process

FYI,

You will have to clear all of the routers within your domain at the same time, to flush this: https://supportforums.cisco.com/discussion/9452331/how-do-i-clear-dna-entries-ospf-database
