I have 2 dogs. How do I handle situations where one of my dogs inappropriately overcorrects the other one?

Hi Cindy! I have a 7 year old female fixed lab mix who is balanced, social, and all around great dog. I also have a 3 year old male hound mix (fixed) who has struggled with reactivity. I am very proud of our training with him - he is now neutral to dogs, people, and other previous triggers and his obedience is very strong. In this training, we did a lot of groundwork to provide structure and leadership in our home.

However, infrequently (once a month or so), my younger dog will correct my older dog for coming into his space or as a redirection when they are highly stimulated and in a tight space. He needs a large personal bubble and we manage situations to make sure he doesn't go over threshold. However, sometimes he will correct her and, in my opinion, it is an over correction when she didn't do anything that warrant a strong correction from him. I don't like that the young dog over corrects her in a non-appropriate context. How should I handle these situations? Thanks!
