If our plugin is not insalled correctly, it might be that there are labels like 'com.k15t.scroll.pdf.ui.export.dialog.customize.settings' in the UI instead of the right UI-element:
- All Scroll add ons
- All versions
- Re-install your Scroll add on.
- Optional: restart your Confluence system.
The labels should now be displayed as correct UI elements.
- The add on wasn't installed correctly.
