Can't make changes to interface method declarations after implementing them in Blueprints

Wow, that’s a weird behavior. But it works now, so thank you.
In the end i opted to use FString as a parameter but the weird thing is that it still requires to be const address, which leads me to question how UHT determines interfaces, if you have any knowledge of this i would be happy to hear it
As for removing UFUNCTION macro i could only remove it in the derived class that implements the interface, NOT in the interface (that’s for anyone who’s looking for answers)
And yeah as for why i wanted to use UWorld i have a TMap of all levels that can load but didn’t think of simply using FString to find by key which is honestly my fault

The end result:

BaseLevelManager.h

#include "CoreMinimal.h"
#include "UObject/NoExportTypes.h"
#include "BaseLevelManager.generated.h"

/**
 * 
 */
UINTERFACE(BlueprintType)
class UBaseLevelManager : public UInterface
{
	GENERATED_BODY()
};

class IBaseLevelManager
{
	GENERATED_BODY()

public:

	UFUNCTION(BlueprintCallable, BlueprintNativeEvent, Category="Interface")
	void LoadMainMenu();

	UFUNCTION(BlueprintCallable, BlueprintNativeEvent, Category="Interface")
	void UnloadMainMenu();

	UFUNCTION(BlueprintCallable, BlueprintNativeEvent, Category="Interface")
	void LoadTargetLevel(const FString& TargetLevel);

	UFUNCTION(BlueprintCallable, BlueprintNativeEvent, Category="Interface")
	void UnloadTargetLevel(const FString& TargetLevel);
};

BaseGamemode.h

UCLASS()
class PROJECTREBIS_API ABaseGamemode : public AGameMode, public IBaseLevelManager
{
	GENERATED_BODY()

public:
	UPROPERTY(BlueprintReadWrite, EditDefaultsOnly, Category="Default")
	TMap<FString, TSoftObjectPtr<UWorld>> LevelsArray;

	UPROPERTY(BlueprintReadWrite, EditAnywhere, Category="Default")
	UWorld* CurrentLevel;
	
public:
	UFUNCTION(BlueprintCallable, BlueprintNativeEvent, Category="Interface")
	void LoadMainMenu();
	virtual void LoadMainMenu_Implementation() override;

	UFUNCTION(BlueprintCallable, BlueprintNativeEvent, Category="Interface")
	void UnloadMainMenu();
	virtual void UnloadMainMenu_Implementation() override;

	void LoadTargetLevel(const FString& TargetLevel);
	virtual void LoadTargetLevel_Implementation(const FString& TargetLevel);

	void UnloadTargetLevel(const FString& TargetLevel);
	virtual void UnloadTargetLevel_Implementation(const FString& TargetLevel);
};
