Some users ask us why the JIRA issue name is not updated when the bullet is updated. The reason for this is because it is possible to link a bullet to multiple issues. When you create a JIRA issue from Delibr, we populate the issue name field with the bullet text. However, we don't sync the name if you, later on, change the bullet text.
If this is a feature that you would like to have, please let us know, and we can consider adding it to our roadmap.
