Environment

Steps to Reproduce

• Make sure, you have New Jira import wizard screen [as displayed below]
• Select either of option "Jira (software project) or "csv"
• In "csv" option, upload a CSV file to import issues in existing project and click on next button
• "On Set up a project in jira" screen , select project type [business/software project] and enter project name of existing project where we need to import the Jira issues.

Expected Results
