Then, what types of issues are listed, such as a bug, new feature, task, sub-task, story, or epic, which is an issue ticket that represents an overarching project?

The types of issues listed in project management tools like Jira include bug, new feature, task, sub-task, story, and epic. A bug is a problem that needs fixing, a new feature is a request for a new functionality, a task is a piece of work to be done, a sub-task is a smaller part of a larger task, a story is a user-focused feature, and an epic is a large body of work that can be broken down into a number of smaller tasks or stories. Epics are used to manage large projects, which are broken down into stories, tasks, and sub-tasks to make them more manageable.
