When a new module is inserted into a page layout, it is set with a predefined placeholder text.
To deactivate this behavior, follow these steps.
Expand the Visual Builder settings bar by clicking on the three dots icon
Open the Builder Settings by clicking on the icon with three vertical dots
Deactivate the Add Placeholder Content To New Modules option.
Once the preferred view mode is changed, save the page to save the new selection.
Note: The placeholder text will not be used the next time a new module is added to a layout.
