Unpredictable Rewards in Stable Baseline 3 DDPG and TD3 Models - Seeking Clarification

Hello,

Thank you for creating the library, and I appreciate your excellent work.

I've been experimenting with the Stable Baseline 3 DDPG and TD3 Models. When I run the training script, I'm experiencing unpredictable rewards, sometimes they calculate correctly, and other times they stay at 0. If I stop and rerun the script, the rewards may still be 0. Could you clarify if this is an inherent issue with the models or if I should review the code?

I'm using one week of 1-minute data for a single stock in my training.

Best regards
