Some designs DO NOT SILENCE the other channel fully. The balance knob is not to create one channel mono. just 'balance'. So I would suggest if you manage to get in touch with the company, they will tell you that is how they designed it.
Good luck.
When the op writes "as it should'. You are not really saying it must, (or it is not a balance control) you are saying it is what you EXPECT. Sorry that the device does the job (balances the signal), but not what you expect. (shuts off the other channel completely)
