@eugenealegiojo — If you delete posts or make substantial changes to your posts (ie. permalinks, post titles, images) then you’ll need to reindex your site. Have you already reindexed?
If you still need more help, please let us know your site URL so we can take a look.

Thanks Katrina.
Is it necessary to reindexed? No way to automatically update?
Please note: as of Wednesday December 31, 2014, the nRelate plugin will officially be switched off. Please deactivate, and remove it from your site before then, as it will no longer work. For more details, please visit our blog: http://nrelate.com/content/2014/12/01/farewell/
