How can I change the block substitution to match the dimensions of the block in the Simulink model

In "linearize(modelname,io)" using block substitution the input-output dimensions of the substituted block linearizations the input-output dimensions of the block being replaced. The block substitution for pv_hybrid_phd_model/3-Phase Dynamic Load/Model/Discrete/Unit Delay2 has dimensions [1 x 1] and the Simulink block has dimensions [2 X 2]. Change the block substitution to match the dimensions of the block in the Simulink model.

Why no answer on this question? I am facing the same difficulty using the control system tuner for PMSM drive. Simple PI controller is not getting tuned by control system tuner and this same messgae is flashing over and over. Kinldy help on this issue.
