Console unable to make changes

I'm using Serviio on Synologi NAS and I have also installed the Serviio Console to set up the behavior. Today I wanted to change settings like: adding online source, adding/removing local folder or just same simple things like that. After I pressed Save to changed settings (it says "Saved!") the window reloads but the changes are lost and everything stays as it was before.
Also when trying to add a local folder, in opened dialog, it is impossible to select local folders.
DSM vesrion: 4.3.3776
Serviio version: 1.2.1-0019
Serviio Console version: 1.4beta-002
Java SE for embedded 7 version: 1.7.0_21-0017
What can I do to make my changes saved?
