error "Wire: is a member of a cycle

I am doing decoupling control of MIMO system in LabVIEW Control Design and Simulation module. Simulating the controller and the plant transfer functions, gives the error "Wire: is a member of a cycle".I understand this is coz of the Three transfer functions in the trnsfer matrix having equal number of poles & zeroes showing Direct feed through behavior. As I can make no changes in the plant or controller models, can anyone suggest a possible solution for this?plzz
