When I try to run the clean up feature it deletes all the news, including the one that are less than 90 days.
Maximum age of news in days to keep 
Maximum number of news to keep [off]
Delete read news [on]
Never delete unread news[on]
Never delete stared news[on]
Never delete labeled news[off]
Clean up 'Deleted' [on]
Purge DB [on]
These are my settings.
I ran db integrate check in SQLite and found no errors
