If it shows up in the parameters tab but not in the shaping tab then it’s been done “poorly”.
With Genesis selected open the Property Editor, find the morph that isn’t showing up and right click it, select “settings” and then “Presentation”, near the top of the new window you’ll see “Content Type”, the line under that needs to say “Modifier/Shape” for it to show up in the shaping tab, you’ll be able to change it as long as DS4 and the CMS are talking to each other, if their not it’s a text editor.
You now need to write your changes into the file, you do that using the Property editors options menu (top corner of each tab, little triangle with 4 white lines), and select “save modified assets”, or by going “File > Save as > Support Asset > Save modified assets”.
