Multiple form submissions not recorded in Mautic

Your software
My Mautic version is: 5.1.0
My PHP version is: 8.1
My Database type and version is: MySQL

Your problem
My problem is:

I run a real estate firm, and each property has a unique form which if a client is interested they will submit their details and an auto email will go out to them.

The auto emailer is the same, and they segment has been created, if it a brand new lead it comes in and sends the email. But I have configured Zoho CRM to create a new lead each time a form submission is done and the source is what determines which email to send.

Since a client has already filled in a form the first time, if they do it again, Mautic does not import that new lead for it to send that specific email.

Steps I have tried to fix the problem:

I have removed email as the unique identifier. I am using Mautic installed from Cpanel and all corn jobs are set up.

Please can you assist
