I am having a problem trying to get my entities mapped using Automapper.

I already have the following mappings where 'GearLevel' has a collection of 'Gear' and there will always be 6.

When i map the entities, if the 'Gear' has multiple entities with the same name it only maps one of them so i will only get one of those entities mapped.

Should i be doing something else in my mappings to overcome this and if so how do i configure it?

 CreateMap<HeroViewModel, Hero>();
 CreateMap<TagViewModel, Tag>();
 CreateMap<AbilityViewModel, Ability>();
 CreateMap<StatViewModel, Stat>();
 CreateMap<GearLevelViewModel, GearLevel>();
 CreateMap<GearViewModel, Gear>();

 CreateMap<HeroViewModel, RegisterNewHeroCommand>()
 .ConstructUsing(c => new RegisterNewHeroCommand(c.Name, c.Damage))
 .ForMember(dest => dest.Tags, opt => opt.MapFrom(src => src.Tags))
 .ForMember(dest => dest.Abilities, opt => opt.MapFrom(src => src.Abilities))
 .ForMember(dest => dest.Stats, opt => opt.MapFrom(src => src.Stats))
 .ForMember(dest => dest.GearLevels, opt => opt.MapFrom(src => src.GearLevels));

I am calling the AutoMapper in the following code and when it calls the mapper the 'viewModel' has all the 'Gear' in the 'GearLevel' but when the 'registerCommand' returns it is missing multiple 'Gear' in the 'GearLevel' with the same name.

public async Task Register(HeroViewModel viewModel)

 try
 
 var registerCommand = _mapper.Map<RegisterNewHeroCommand>(viewModel);
 await _mediator.SendCommand(registerCommand);
 
 catch (Exception exception)
 
 _logger.LogError(exception, $"Failed to register 'viewModel.Name'");
 

This uses the following entities:

public class HeroViewModel

 public Guid Id get; set; 
 public string Name get; set; 
 public int? Damage get; set; 
 public List<TagViewModel> Tags get; set; 
 public List<AbilityViewModel> Abilities get; set; 
 public List<StatViewModel> Stats get; set; 
 public List<GearLevelViewModel> GearLevels get; set; 


public class GearLevelViewModel

 public Guid Id get; set; 
 public int? Level get; set; 
 public List<GearViewModel> Gear get; set; 


public class GearViewModel

 public Guid Id get; set; 
 public string Name get; set; 

And the following commands:

public class RegisterNewHeroCommand : HeroCommand

 public RegisterNewHeroCommand(string name, int? damage)
 
 Name = name;
 Damage = damage;
 


public abstract class HeroCommand : Command

 public Guid Id get; protected set; 
 public string Name get; protected set; 
 public int? Damage get; protected set; 
 public List<Tag> Tags get; protected set; 
 public List<Ability> Abilities get; protected set; 
 public List<Stat> Stats get; protected set; 
 public List<GearLevel> GearLevels get; protected set;
