Security Analytics alerts missing after upgrading to OpenSearch 3.7.0 / Only shows single detector alerts

Versions (relevant - OpenSearch/Dashboard/Server OS/Browser): 3.7

Describe the issue: Hi everyone,

I recently upgraded our environment to OpenSearch 3.7.0 and I am running into a critical issue with Security Analytics.

Since the upgrade, almost all of our alerts have disappeared. Currently, the system only displays the alerts belonging to a single detector.

Interestingly, if I turn this specific detector off and back on, it remains the only one showing active alerts. The rest of the detectors do not seem to surface their alerts anymore, even though they should be triggering.

Has anyone else encountered this behavior after the 3.7 upgrade? Any advice, troubleshooting steps, or workarounds would be highly appreciated!

Thank you in advance for your help.
