CMC - How to decrease Residual forces?

Hi everyone,
I'm trying to run the CMC tool but I obtain Residual values really too high (see plot attached) compared to reference values given from OpenSim documentation, even if after I have applied the RRA tool I obtain good Residual values (always according to reference values). Also, the kinematics traking errors and the reserve actuators values are good. I attached all the plots so you can see the results I obtained. Do you know how I can improve my results?
Thank you so much.

The example The Strength of Simulation: Estimating Leg Muscle Forces in Stance and Swing can be helpful in learning how to best use RRA and CMC and reducing residuals.

Hi, AddBiomechanics is capable of reducing the residual forces and moments further than RRA:
