Make nullables dublicates of the mappings (And ignore settings of my mapper)

See original GitHub issue

Following the documentation - i made internal mapper to convert properties of the object:

[Mapper(UseDeepCloning = true)]
public static partial class PortfolioMapper
{
    public static partial GetPortfolioResponseDto ToGetDto(this Portfolio source);

    [MapperIgnoreSource(nameof(Agreement.Portfolios))]
    [MapperIgnoreSource(nameof(Agreement.Client))]
    private static partial GetAgreementResponseDto ToGetAgreementResponseDto(Agreement source);

    [MapperIgnoreSource(nameof(Client.Agreements))]
    private static partial GetClientResponseDto ToGetClientResponseDto(Client source);
}

Code Generated includes “?” for nullables for the Portfolio class

But also for the Agreement class where i configured ignore settings for the Client property:

So it uses nullable version of code-generated mapper and doesn’t pick up my configuration.

To Reproduce So I’ve tried to reproduce the bug, but in small project it works fine - it doesn’t create nullable duplicates.

Environment (please complete the following information):

Mapperly Version: 2.6
Target Framework: net7.0
OS: Windows10

Original Classes:

public class Agreement
{
    [Key]
    public int AgreementId { get; set; }

    public Client Client { get; set; }
    public string Code { get; set; }
    public List<Portfolio> Portfolios { get; set; }
    public DateTimeOffset Date { get; set; }
    public DateTimeOffset? TerminationDate { get; set; }

    public bool IsDeleted { get; set; }
}

public sealed class GetAgreementResponseDto
{
    public int AgreementId { get; init; }
