Why does Create Diagonal Matrix block not return the diagonal matrix in Signal Processing Blockset 6.1 (R14SP1)?

I have a simple complex vector as an input to the Create Diagonal Matrix block in Signal Processing Blockset 6.1 (R14SP1). When I check the output matrix in the Display block it has some non-zero off the main diagonal elements.
