Hey @jessestarrphoto,
What happens when you manually Option-Click the Notification Icon in the Menu Bar?
On macOS Sierra10.12.6 this will toggle the DND status On/Off.
Mojave has played havoc with macOS automation in a variety of respects in the name of security.
Try this macro:
Option-Click Notification Icon v1.00.kmmacros (6.4 KB)
If it works then you should be able to incorporate it into the other macro.
