Agent Manager was not created for behavior_id

When I start the training of the agents, it says:

2020-06-06 22:43:15 WARNING [env_manager.py:109] Agent manager was not created for behavior id DefenderShopAgent?team=2

Unity and Anaconda Prompt doesn't give any errors. But the agents do not train. Solution?

Is this an asymmetric or symmetric game i.e. are the agents on team 0 and/or 1 also a DefenderShopAgent? Can you send your trainer config?
