**Your software**  
My Mautic version is: 4.4.9  
My PHP version is: 8.0.30  
My Database type and version is: MySQL 8.0.23

**Your problem**  
My problem is:  
I’m having an issue when trying to apply a filter within segments.  
I want to view all users who have a null birthdate in the database, but when I use “empty,” it doesn’t return any contacts, even though I know there are many null entries in the database. Is there another way to filter this data to retrieve null values?  
Please note that it’s a ‘datetime’ field.

These errors are showing in the log:  
There’s no error log; it simply doesn’t fetch any results.

Steps I have tried to fix the problem:  
I attempted to filter using ‘is empty,’ but it doesn’t provide me with any results.
