Missing savedAgentResultStruct after certain episodes

I used DDPG agent to train an agent and set the saving criteria for the agent as episodic reward. Agent's above the threshold are saved. However, savedAgentResultStruct is not saved for all the agents. It is saved for a few agents in the beginning and then only the saved agent. What should I do to prevent this and save all the agents with savedAgentResultStruct.

I am using MATLAB R2021b

This isn't the intended behavior. Can you please create a tech support case?
