I have a CK-BL602-4SW-HS-03(139)-1 switch with two channels. When one of the channels is on, the icon says “1 On 1 Off”. Inside, the switches correctly show the enabled channel (left or right). I suggest that for the case of ONE RIGHT CHANNEL being on, the icon display the information “1 Off 1 On” and for the case of one left channel being on, leave it as is “1 On 1 Off”.
