We recently released a fix for an issue that was occurring when editing detection filter operators. The bug caused the detection filter to fail after saving. For example, if you had created a filter that was using the "EQUALS" operator and changed it to "CONTAINS", the findings would still be generated.
This behavior is still possible if you edited a detection filter prior to November 15, 2022.
We recommend that you create a new filter with the preferred operator and delete the previously saved filter.
