Custom shortcode being shown in WPBakery backend rather than the block

since the last time I used WP Bakery, shortcodes were not rendered in the back end (unlike with elementor for example). If it also shows it like this in the front end, then you need to make sure that you selected the ‘text’ tab and not ‘visual’ for the text-block you added the shortcode to (on the visual it sometimes escapes the brackets).
