V1.6.2x - Enums duplicate in schema

[JohnGalt1717]

Describe the bug
The same enum with the same location is being added to the schema as ContactTypes and also ContactTypes2. They're referenced from different models, but should have been recognized as the same because they're the same type.

OpenApi File To Reproduce

openapi (1).json

Expected behavior
Should have the same enum no matter what in the schema.

Additional context
Add any other context about the problem here.

Here's the dto that is fine:

public readonly record struct ContactRefDto : IRefDto
{
    public required string Name { get; init; }

    public required string? AvatarUrl { get; init; }

    public required ContactTypes ContactType { get; init; }

    public required Guid Id { get; init; }
}

Here's the dto that induces the duplicate:

public readonly record struct UserRefDto : IRefDto
{
    public required Guid Id { get; init; }

    public required string Name { get; init; }

    public required string? AvatarUrl { get; init; }

    public required Guid OnBehalfOfId { get; init; }

    public required string OnBehalfOf { get; init; }

    public required ContactTypes OnBehalfOfContactType { get; init; }
}

Doesn't matter if they're standard records or record structs.
