In order to force users select the correct Issue Type, is configured Default Issue Type as None, but when users click on create a new ticket Issue Type brings the last issue type selected instead of None, which means option None doesn't work as expected. If the user has never created a ticket before or just switched projects None will default to the top Issue type in the Issue Types for Current Scheme.
- Login JIRA as Administrator;
- Navigate trough Issues >> Issue Type Scheme;
- Select None in Default Issue Type;
- Create an user;
- login JIRA with new user;
- Try to create an issue.
