How do I get rid of bugs switching between Cyan & Denim (Lumia 625, India)?

Bug! Switching between Cyan & Denim (Lumia 625, India) ! Cortana US became different!

I got the updates through Preview for Developers. But, When I unenrolled and uninstalled the app "extras+info" showed it's Lumia Denim. Got The Folders on start screen, 4G option for network. But Cortana became different too. For example previously when I asked Cortana about any Celebrity or anything else she used to give a brief info by saying "______ is an........" . But Now, it says "Here is what I found". For sometimes the Music recognition option on Cortana screen appeared, again vanished. After that, I reenrolled for PFD and it went back to Cyan but with same features. But during this process when I checked for phone updates it didn't show any result. It carries on checking for updates.
Is there anything to solve the problem apart from Lumia Recovery Tool?

This is not a problem. Since Denim carries no firmware changes for older phones its identical to preview and thus when u unenroll from preview provided u already got the latest 8.1.1 it shows as denim in extras + info and some denim goodies appear.
It been like this for a few months now
