Hello,
What is your WP role: editor or admin? WPBakery has known issue with WP roles and does not allow to use WPBakery for the custom posts types if you logged in as the editor or store manager etc, only for admin. So, try to login as admin and check if you have the editor buttons.
I have passed the problem with topic creation to our developers. They will check and I’ll inform you about the answer.
Regards
