1.How did you found the user data missing under registry key? Is there any error message received?
2.Per my search, the first time that a package is run by any user on the OS, the complete registry staging occurs. It is at this time, delaying the app launch, which the pre-staged DAT file is read and a copy of its contents is placed under the key:
HKLM/SOFTWARE/Microsoft/App-V/Client/Packages/PkgGUID/Versions/PkgVerGuid/REGISTRY
This is a read-only copy used by the client.
3.Below is a blog related to "User Registry Setting missing 06-0000000E" for your reference:

Hope this helps and please help to accept as Answer if the response is useful.
Thanks,
Jenny
