@immermanalu I did it and I am still seeing the same thing on my webpage. But on the Facebook debug tool it shows correctly. Anyways, I managed to track the source of the problem as the editor I’m using when creating articles. If I use the editor from /wp-admin/, this happens when articles. Since then I wrote more articles using wordpress.com editor and when I create them from there, they show correctly when sharing. Guess I’ll just keep using the last one.
Thanks for the help anyways!
