Thx, that is what I already thought. No problem, back to GUI configured things now 
BTW, if anybody is still looking for changing the invert percent for rollershutter devices in the things file:
Thing zwave:fibaro_fgrm222_24_024:controller:node11 "Z-Wave Node 11: FGRM222 Roller Shutter" (zwave:serial_zstick:controller) [ node_id=11 ] {
Channels:
Type blinds_control : blinds_control [ config_invert_percent=true ]
}
