Not possible to save first config after installing

[Phaiax]

After installing the extension for the first time, and creating an initial configuration, this configuration can't be saved. The parameter "derived from config" (or so) is highlighted in red, even though it's written "optional" next to it. The drop down is empty because no config exists.

Solved this by editing the workspace configuration file and removing "extend" inside Settings->"sshfs.configs"
