What is the expected output? What do you see instead?
I expect to see the existing profile copied to the new one, instead it resets the copied profile, destroying it.

What version of the product are you using?
The latest.

Do you have an error log of what happened?
There was no error log?

Please provide any additional information below.
It deleted my entire UI setup, i was going to copy my mains UI setup, add a XP bar to a new one for leveling alts, instead I have to make a entire new UI setup, extremely painful bug, please fix asap.

Edit: Improved steps

Works perfectly for me.
The copying is also well tested and its rather unlikely that it can delete or reset the source profile. My guess is that some other addon or something interfered.

I'm betting its because it was a very old profile that i had been using since early MoP. I can't really test it now because my sub ran out and the addon is currently unusable on 6.1.

I also had downloaded and used bartender beta during the last few weeks of MoP, so im guessing if its not broken for anyone else those would be the causes.

I'm only using DBM, Ackis recipe list, SexyMap, Scrap, Skada, Raid Achievement, Prat, npcscanner, CollectMe, Bagnon, Masterplan, Handynotes, quartz and postal otherwise, which are all mainstream addons aswell. All fully updated.
