Changes to the group configuration do not become permanent until you save them. To immediately reflect the saved group configuration changes on the project components, reload the attribute group cache.
When you have unsaved changes, you can use Revert to Last Save to undo those changes.
To save the current group configuration, click Save.
When Studio first loads the project data, it stores the attributes and groups in the cache. To reload the cache, so that the project components immediately reflect any updates to the group configuration, click Reload Attribute Cache.
