Seem to be having a problem setting things up on latest git.

I can change lnb type to uincable fine and saves ok. Changes show in config for the adapter and there is info in debug the log.
But when I go to setup the lnb settings it self it don't save. The tree closes as if it saved but logs show noting and config file for adapter is not changed in any way.

Seems to be just with the unicable settings as I can change the settings on the lnb it self under different lnb types.

The config it self after I change to unicable looks a little odd. lnb settings are there tiwce
