I added snacks at one time so I know I did the process right. Today I added the 4 RoS travel baubles and they verify in the DarqUI gear macro window.

If everything looks right in the utility, and you have either closed the utility or clicked Autosave, then they should appear when you restart the game or use /loadui. Look in the in-game window manager and see if they appear there.
