Hi @박현홍 Welcome to the Atlassian Community Forums?
Would it be possible to ask your question in English? That would benefit other community members to help you answer your question.
From what I can understand (from Google Translate), you are trying to re-create a custom field with the same name but the data from the deleted fields has not been restored.
You asked the question the Jira Align product group. Can you confirm that your question is for this product and not for Jira?
