User Guides
1. View all labels in one place
In order to view all labels and number of issues under a specific label, click on Manage Labels tab on left sidebar in your Jira project.
2. View all issues under a label, rename or delete a label
Once in overview page, click on label name. It will show all issues under the label and option to change name or delete the label entirely.
Please note: Changing name or deleting a label is limited to current project. If you are not able to do such actions, it is likely that you are in different project. Just switch the project and you should be able to use those features. This is to prevent users accidentally deleting or renaming labels in other projects.
