Don't duplicate posts
When you enable the TieLabs Builder by clicking on Use the TieLabs Builder button, the Don't duplicate posts option will appear in the Jannah - Settings options box below of the page builder section,
Jannah - Settings > General > Don't duplicate posts, check it in if you want to make sure that any post will be displayed once on this page.
Note: This option doesn't work with the AJAX pagination option in the blocks.
