Missing web-hook and email invocations for Grafana Alerts

We have several user organizations for which we create the same alert rules. In the triggering history, it can be seen that the firing states in both organizations are being worked out. However, only one request comes to the webhook of our application, where there is data for only one alert rule for one organization. I would like to understand what this is connected with, how the queue for sending alert rules is formed, and is it possible to see the graphana logs to troubleshoot?
