Hi,
This solution solve the problem for Jetpack/Publicize plugin
Adding “_wpas_done_all” to the “Do not copy these fields” line on the Duplicate Post Options page
Try that or ask “NextScripts: Social Networks Auto-Poster” developers about the string that saves the post meta and put it in “Do not copy these fields” line on the Duplicate Post Options page
Because “Duplicate Post” copies the post meta information to the new post and considered as shared
