Thanks for all of your help and suggestions. Apparently, this is a known issue which would have been apparent if I had sent a shot of the block connections. Trying to use the auto-connection to hook up an expression block instead makes self-connections on the recursive blocks. All of you probably knew this, but that way of connecting doesn't quite work the same. Disconnecting the self-connections and properly wiring the block to an expression block seems to have fixed the problem.
