Deleted files are restored

Expected behaviour

When deleting files/directories in a shared directory, the files must be deleted for all users and not restored

Actual behaviour

Example. There is a directory of files that is accessible to 10 people. When file X is deleted by user A on the web, the file is moved to the trash. After a few minutes, the file appears again. The events indicate that it was downloaded from user B

Steps to reproduce

  1. Create directory
  2. Share to more than one person
  3. Connect people using owncloud clients
  4. Add file to directory
  5. Delete file

Hey,

this looks to me like a quite outdated version of ownCloud (this has been released on 2023-05-31).

Maybe you could update to the most recent version 10.13.4 first to see if this is already solving this problem (maybe there was e.g. a bug in ownCloud causing this)?
