Multiple problems in Tanks! tutorial...

I tried to make the TANKS! game according to the tutorial. but after the 7th phase which takes care of the managers I ran into some problems.

1st The camera suddenly doesn't adjust anymore, which it did before. 2nd Only one tank spawns, although both spawns are set, it also doesn't color blue but stays green. 3rd The title (TANKS!) stays in the screen all the time and there are no rounds announced..

I really don't get what I did wrong, I ran through all the code and it seems to be exactly the same, I also filled everything in the inspector.

the only thing I changed was uncomment this line:

3 using UnityEngine.SceneManagement;

so that it wouldn't give me an error about SceneManager not existing...

thanks for any help beforehand :3
