Upgrading a release candidate to a final version doesn't work
When you want to upgrade for instance 1.13.0-rc1-j500 to 1.13.0-j500, nothing happens.
The reason is that the UPM considers 1.13.0-rc1-j500 more recent than 1.13.0.
Uninstall the add-on and reinstall it from the marketplace. This will not affect your grid configurations.
