Backup Manager Beta is not remembering password in destination

[maquinadigital]

I have the latest CWP update and, since a couple of days ago, all servers forgot passwords.
Retried and I can't get cwp to remember the passwords.

But I'm not also sure it's just that... even the password test (ftp) shows as OK and, checking the NAS logs, it's invalid... But using shell to FTP from the server to the NAS works

There's something changing the actual password. I even removed special chars to test it and no luck.

CWP please, instead of making a better looking panel, just make Backup NEW work properly.
The main backup is not enough (we need retention) and the other has been beta forever
