CurrentValues.SetValues() not working for nested objects

I have the following methods on a repository:

public async Task<T> AddAsync(T entity)
{
    await _dbContext.Set<T>().AddAsync(entity);
    return entity;
}

public async Task UpdateAsync(T entity)
{
    var selected = await _dbContext.Set<T>().FindAsync(entity.Id);
    if (selected is not null)
        _dbContext.Entry(selected).CurrentValues.SetValues(entity);
}

I have the following entity:

public abstract class AuditableEntity<TId> : IAuditableEntity<TId>
{
    public TId Id { get; set; }
    public string? CreatedBy { get; set; }
    public DateTime? CreatedOn { get; set; }
    public string? LastModifiedBy { get; set; }
    public DateTime? LastModifiedOn { get; set; }
}

public class Customer : AuditableEntity<int>
{
    public int Title { get; set; }
    public string FirstName { get; set; }
    public string LastName { get; set; }
    public Address Address { get; set; }
    public Contact Contact { get; set; }
    public int LeadSource { get; set; }
    public IList<Order> Orders { get; set; }
}

public class Address
{
    public string? Number { get; set; }
    public string? Postcode { get; set; }
    public string? Street { get; set; }
    public string? Locality { get; set; }
    public string? Town { get; set; }
    public string? County { get; set; }
    public string? Country { get; set; }
}

public class Contact
{
    public string? Mobile { get; set; }
    public string? Home { get; set; }
    public string Email { get; set; }
}

DB context configures the following behaviour for Customer:

builder.Entity<Customer>()
    .OwnsOne(o => o.Address);
builder.Entity<Customer>()
    .OwnsOne(o => o.Contact);

Calling AddAsync successfully adds the entity to the DB, calling UpdateAsync will update only the top level non nested properties.

When I try to update the entity with a new Address or Contact, the values aren’t updated. But if I update FirstName it works fine. Should this be working as I expect or am I missing something?

@ScottKane SetValues works on a single entity instance. It does not set values for related entity instances.

@ajcvickers well I’m using it to do that and it definitely is updating the related entity. I’m assuming this is because a Customer owns an Address so it’s effectively treaded as part of the entity? I’m never using this to update a one to many relationship as there is a separate API for the child entity to be updated.
