Description

Whenever creating issues or a project using the External System Import feature, Jira may automatically select an invalid issue type if the instance contains multiple issue types with the same name (which may happen if next-gen projects exist).

How to reproduce

1. Go to Jira Settings > System > External System import
2. Select CSV
3. Choose the Defined in CSV option to create a new project in the process
4. Upload the file that contains both the project's and issues' definitions
5. Map the fields accordingly
6. Import the issue

Expected Behavior

• In case the Issue Type Scheme contained multiple records of the same issue type (one from a Next-Gen project and the other a "regular" issue type, Jira should recognize the proper issue type to be used

Actual Behavior

• Jira chooses the incorrect issue type to be used, causing the issue to use an invalid issue type
  
  • The Story issue type in the picture is from a Next-Gen project
