Two alerts fired within five minutes of each other

There are multiple rules configured with alert evaluation behaviour -
Every 1 hour for 0 hours
Notification policy timing has stayed the same.
Within 5 minutes, each alert fires twice.
They should fire once every hour.
Is there a way to resolve this?
After changing from Normal to Alert, the alert stays in alerting state the entire time. Isn’t it supposed to go back to the Normal state while evaluating and then become alert again?

THANK YOU!!
