Hello,
WoodMart works with either WP Bakery builder or Elementor builder at once, but not with both at the same time. In the process of the installation of the plugin, please install one building plugin, you are going to use. It is not possible to convert an existing site that is built on WP bakery page builder into Elementor. In order to have a site basing on the Elementor builder, it is necessary to replicate the site from scratch on a new WordPress installation with the Elementor plugin.
If you have any questions please feel free to contact us.
Best Regards
