If you want to continue to use Essential Graphics like the Legacy Titler, you need to upgrade the Essential Graphic to become a Source Graphic.

You can use the Upgrade to Source Graphic (previously known as Upgrade to Master Graphic) option to create a Source Clip (previously known as Master Clip) item in your Project Panel from a graphic clip in your sequence.Any new graphics made from a Source Graphic, including the one you upgraded from, are always exact duplicates of each other. This include the source text string. Any changes made to the text, style, or contents in an instance of a Source Graphic get reflected in all other instances of the Source Graphic.
To create a Source Graphic, select Graphics > Upgrade to Source Graphic.More info how to upgrade Legacy Titles into Source Graphics:
