Update RefNotes tag

Is there an update RefNotes Callout somewhere? I've renumbered our callouts and the schedule is correct but some of the tags were not updated. When I "Edit Object" the category doesn't show up. I can select it from the dialog box's pull-down and reset it, but it doesn't show up differently in the callout. Then when I run a schedule, it is correct. But when I go to "Edit Object", the category is gone again in the dialog box. Weird.
