Two different things share the word "service" — this note clears up which is which.
- Dive-service types and categories (Course, Course bundle, Activity, Activity bundle, dated trips, plus display categories like Beginner or Fun Dive) are chosen per service on the service itself, in the Dive Menu. That's what groups your offerings on the booking page.
- Settings → Service Job Types is a different feature: it configures equipment-servicing jobs for the servicing counter, not dive services. See service-job-types.md.
