bUpdater registry key is reset to 0 after autoupdate

We recently rolled out an autoupdate version of the Adobe Acrobat Reader DC on a few testclients. Before that we used fixed versions where the update feature was disabled via the FeatureLockDown settings.

After the installation of the autoupdate version the registry keys needed for autoupdate are all set to 1 (as intended):

HKEY_LOCAL_MACHINE\SOFTWARE\WOW6432Node\Policies\Adobe\Acrobat Reader\DC\FeatureLockDown\bUpdater
HKEY_LOCAL_MACHINE\SOFTWARE\WOW6432Node\Policies\Adobe\Acrobat Reader\DC\FeatureLockDown\cServices\bUpdater

HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Adobe\Acrobat Reader\DC\FeatureLockDown\bUpdater
HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Adobe\Acrobat Reader\DC\FeatureLockDown\cServices\bUpdater

And this works fine for the first update. The reader updates itself to the newest version after some time. The problem is that the bUpdater values are reset to 0 after the update, thus preventing future autoupdates.

Is there a setting in the Adobe Reader to prevent this behaviour?
