Automatic merging companies. How it works?

Your software
My Mautic version is: v4.4.10
My PHP version is: 8.0.30
My Database type and version is: 10.4.34-MariaDB-1:10.4.34+maria~ubu2004

Your problem

After creating a company through the API with companyname = “ab” Mautic returns company_id = 4782

After creating another company through the API with companyname = “a” Mautic returns the same company_id = 4782

Mautic is merging two different companies to the same entity!!!

Can anybody explain this merging criteria?

Is it possible to work without the unique identifier (companyname) to avoid this behavior?

Best regards
