Simulation with an RL Agent does not save simulation data

I have a reinforcement learning simulink model environment I am training in MATLAB 2023a, which I started porting to MATLAB 2024a. The model runs well in 2023a and saves the simulations done using the sim function. The environment has some signals that I want to save.

For the 2023a they got saved in the SimulationInfo object but that doesnt happen with 2024a. Do I have to activate something additionally in 2024a or is it a bug?

The images below detail the difference between the two versions. The env is a simulink envrionment

simEpisodes = 1;
simOpts = rlSimulationOptions("MaxSteps",1250,...
    "NumSimulations", simEpisodes);
experience = sim(env,agent,simOpts);
save(strcat(results_dir,'/Experience.mat'),"experience")

Based on the release notes for the Reinforcement Learning Toolbox, MATLAB R2024a, the behaviour of “SimulationInfo” property has changed, and the property is now a “SimulationStorage” object.
