Finding new alerts in log investigations | Azure log analytics | KQL language | Azure Sentinel

Hello,

I was doing some investigations in Azure log analytics and when I searched more info on one alert I discovered more alerts that where not on the Incidents page of Azure Sentinel.

The alert type was "Unknown" or "Silent" but the Severity was High .

Is this because of the Analytic rules ?

What can you find during a log investigation that an Analytic rule can miss ?

Thanks
