A minor problem with Endnote 9.3.1 with Catalina

I have been trying out EndNote 9.3.1 with Catalina on Mac and it works fine. I have noticed one small problem, however. In a long manuscript with lots of footnotes, the citations were highlighted in gray, making the EndNote generated citation easy to spot. Now, the gray highlighting is gone. Has anyone else noticed this? Better yet, does anyone know how to fix it?

This should be fixed in Word:

Word –» Preferences –» View –» Field shading –» Always

Hope this helps!
