If you want to have different input limits for the different channels, you need to make sure the channels are listed in separate Channel indexes as well. For example, if your channel array index 0 reads "0:7", then channels 0 through 7 will all use the input limit settings in the input limit array's index 0.
Instead, enter "0" in Channel Array index 0,
"1" in Channel Array index 1, etc.
