**Your software**  
My Mautic version is: 3.2.5  
My PHP version is: PHP Version 7.3.24-3+0~20201103.72+debian9~1.gbp945915  
My Database type and version is: MariaDB 10.5.8

**What I expected**  
HTTP request PUT (/contacts/ID/edit) should not overwrite empty fields with blank when overwriteWithBlank is set to false  
(cf. [Mautic Developer Documentation](https://developer.mautic.org/#edit-contact) ==\> overwriteWithBlank: If true, then empty values are set to fields. Otherwise empty values are skipped)

Language used : NodeJS + Axios module for HTTP requests

**My problem**  
HTTP request PUT (/contacts/ID/edit) request that overwrites all empty contact fields to blank, regardless the attribute overwriteWithBlank set to false.

**Steps I have tried to fix the problem**  
I tried overwriteWithBlank set to true as well, I get the same result. empty fields set to blank.

Can I get some guidance to use the overwriteWithBlank property in the appropriate way?
