My group cleared out a city and we called reinforcements but now when I came back there are enemy ai there again. Any idea what I did wrong?

Is this after a server restart?

Yea. Even though we save it

Are all the modules set correctly to allow persistence? Have you confirmed that persistence is actually working? Are you saving to the cloud or local database?

Persistence is enabled. I have placed blufor units and they are still in the same place.
Its saving to the cloud
