When one setting is done, you can proceed to other Types. In Zendesk, you just have Tickets. It's more complicated on the Jira side, where you have Tasks, Bugs, Stories, and more. If you need them to be integrated, you need to do the mapping. You can use the setting you already did in other type mapping (if you don't want to map users, and statuses again), or you can create a new one.
