AI Being Randomly Added

Okay so I started a 4v4 AI match and for some reason overtime I think 2-3 AI were randomly added, I’m not sure if this is a bug or some weird feature they added, but all I know is that it messes with the spawns and how the AI acts after wards, basically they’ll spawn and they just all sit there bunched together and you have to shoot them to get them to move. I want to know if others are having this “issue”.
