Two different things share the word "service" — this note clears up which is which.
- Dive-service categories (course, fun dive, specialty, package) 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.
