Cosole engine alerts

Very new, non tech, trying to learn
In the console engine, community edition, it says alerts 500, I believe max amount, how do I start as 0 again, tried sudo cscli delete alerts --all, and sudo cscli flush in shell, restarted crowdsec in opnsense, this is on a protecli - opnsense unit
Thank you for your patience

The console alerts are non controllable, we store the last 500 alerts so you will see latest alerts but wont retain any history past that.

Do they eventually go away, or does it update and delete the oldest ones
Thank you for your replies

It updates and removes the oldest ones
