Multiple WBS Gantt-Chart links displayed in administration add-on screen?

Summary

Where Version x.x.6b or later versions of WBS Gantt Chart are installed without first uninstalling Version x.x.6a or earlier, you may see multiple links of WBS-Gantt Chart displayed in the add-on tab of the administration screen.

Workaround

Refresh the administration add-on screen to ensure that only the latest version of WBS Gantt-Chart for Jira is displayed.

If refreshing the screen does not work and multiple links are still displayed, please uninstall the older version and reinstall the most recent version.
