Occ Decrypt doesn't decrypt anything

Hi,
I have an issue with an owncloud 10.0.0.8 installation with encryption (per user) enabled. Am I missing something ?

Thank you.

Steps to reproduce

  1. admin change the password for user1 (using recovery key)
  2. user1 logs in but can’t read his files
  3. admin run occ encryption:decrypt user1
  4. the command run to the end but the files are still encrypted.
  5. i can see in data/user1/files_encrypted some directories with .decrypt containg only keys

Expected behaviour

I expect user1 to access his files now unencrypted

Actual behaviour

the command run to the end but the files are still encrypted.
i can see in data/user1/files_encrypted some directories with .decrypt containg only keys

Operating system: Centos 7

Web server: apache 2.4
