I think I have found the root cause of duplicate app icon problem, thanks to user billyboy who helped me since last month. However, this update will not fix the problem fully if you already have it. A complete reinstall is recommended. But I am sure after this update, you will never get this problem again.
(1) Changed label selector icon size
(1) Improved Backup/Restore
(2) Fixed item keeps showing something went wrong
(3) Fixed menu key disappear in HC system
