Hello,
Let us clarify more deeply. So, posts created in classic mode, as I understand, means that you created a post in Dashboard > Posts, and then display theme via WP Bakery element. Riight?
Now, please describe step by step process of creating posts in WP Bakery. What do you mean? As I understand there are two ways of creating post:
1/ by means of WP http://prntscr.com/j5gal0
2/ by means of WP Bakery http://prntscr.com/j5gaug
What is your way? Do you mean you create post grid with WP Bakery elements? Please give step by step description.
Best Regards
