AI Perception limit sight problem

Hi! I am making an steath game in C++ and blueprint, I have a roaming AI following some points.

I want the AI to only see the player if the player is in a 180º angle in front of the AI, but it seems not working.

I tried to change the peripheral vision angle to 90º or 180º and it keeps detecting me in 360º (When I use the gameplay debugger the green area is in 360º and the update event triggers ).

I’m using a mixture of c++ and blueprints (Since I could not get to work the .AddDynamic).

AIController .h

  UPROPERTY(EditAnywhere, BlueprintReadWrite, Category = "AI")
    UAIPerceptionComponent* PerceptionComp;
  UPROPERTY(EditAnywhere, BlueprintReadWrite, Category = "AI")
    UAISenseConfig_Sight* sight_conf;
  UPROPERTY(EditAnywhere, BlueprintReadWrite, Category = "AI")
    float PeripheralVisionAngleDegrees;
  UPROPERTY(EditAnywhere, BlueprintReadWrite, Category = "AI")
    float SightRadius;
  UPROPERTY(EditAnywhere, BlueprintReadWrite, Category = "AI")
    float LoseRadius;

AI Controller.cc

  PerceptionComp = GetAIPerceptionComponent();
  PerceptionComp = CreateDefaultSubobject<UAIPerceptionComponent>(TEXT("AI PERCEPTION COMPONENT"));
  sight_conf = CreateDefaultSubobject<UAISenseConfig_Sight>(TEXT("AI SIGHT CONFIG"));

  sight_conf->DetectionByAffiliation.bDetectEnemies = true;
  sight_conf->DetectionByAffiliation.bDetectNeutrals = true;
  sight_conf->DetectionByAffiliation.bDetectFriendlies = false;

  sight_conf->PeripheralVisionAngleDegrees = PeripheralVisionAngleDegrees;
  sight_conf->SightRadius = SightRadius; 
  sight_conf->LoseSightRadius = SightRadius + 1;

  PerceptionComp->ConfigureSense(*sight_conf);

AI Char

  UAIPerceptionSystem::RegisterPerceptionStimuliSource(this, UAISense_Sight::StaticClass(), this);

Im quite lost, so I came here to ask for help
