Salesforce plugin: mandatory Lead fields even when Leads is not selected as Object to pull contacts from

Your software
My Mautic version is: 4.4.1
My PHP version is: 7.4.3
My Database type and version is: MySQL 8.0.30-0ubuntu0.20.04.2

Your problem
My problem is: I’ve activated the Salesforce plugin and connected it successfully. On the Features tab of the plugin I’ve only selected Contact as an Object in Salesforce to pull contacts / data from from. The problem comes here: on the Contact Mapping tab it mentions that 3 Leads fields are mandatory for mapping as well while I don’t need/want to map these.
The mandatory Leads fields on the Contact Mapping tab are: Company / Email / Last Name

To me, this feels like a bug. Anyone an idea how to resolve this?

My other settings on the Features tab are:
checked Triggered action push contacts to integration
checked Pull contacts and/or companies from integration
checked Push contacts and/or companies to this integration
checked Use latest updated Do Not Contact record

These errors are showing in the log: –

Steps I have tried to fix the problem: tried to assign them to the same target fields in Mautic as the ones from the Contact Object
