Only channels 30 to 50 (the differential input, VUser0-3 and VAux0-15) are external channels that can be described as "channel@N" child nodes, yet the binding accepts any N from 20 to 50. Listing one of the fixed channels there only makes the driver add it a second time. Limit the child nodes to channels 30 to 50.
