No information in annotation lines (alerts)

Hello everybody,

Since Grafana v8.1.1 the annotation lines do not work like before. Usually, there is an annotation for “OK”, “PENDING” and “ALERTING” in several colors (green, orange and red).
But now every single annotation line is blue and has no information about the status. Also, for some reason, all annotation lines of every single panel are summed up in every panel.
Have a look here:

How can fix this issue?

Thank you a lot!
best regards,

Antonio
