DAQmx Channel property node sets channel properties not in ActiveChans list

I am supplying an array of channel names (using a for loop) to a DAQmx Channel property node via the ActiveChans.  These channels are a subset of channels defined in the task also supplied to the property node.  I am trying to set filter properties on these specified channels and not on the others listed in the task.  However, it appears that the property node is applying the change to the unlisted channels as well because I get an error message saying that I am trying to set a jumper determined filter setting.  I am using SCXI-1520 and SCXI-1121 which don't have the same filter options.  The 1520 is software selectable while the 1121 is not.  The channels for the 1121 are part of the task but not part of the Active Channels array that I am supplying to the property node.   Why is this happening?

Hello ejlittle,

Would you mind posting this portion of your code?  I'd like to take a look at this behavior.

Thanks!

Laura
