matlab recurdyn co-simulation

As shown in the figure, the output value is being checked through Recurdyn and co-simulation through the step block, and a graph that matches the Actual Position graph appears on the recurdyn graph through the transfer function on the matlab.

I want to go up through the transfer function on matlab and check the output angle graph on Recurdyn through output angle gain, but the Actual Position graph keeps showing up.

What's the problem?
