Steps to reproduce
1. Open owncloud app
2. Reload

Files and folders just should show on

Actual behaviour
Shared folders get renamed (actual name + " (2)")

Hi, @TheMineGeek.

ownCloud Android app doesn't rename anything in the server automatically, except when uploading files with a name already in the server. Reload just fetches the list of files for the current folder from the server.

Could you check if the renamed folders appear that way also in the web UI?
