Memory management in cocos2d-x c++

Hi
I am working on cocos2d-x c++(v3.16). I am facing a horrible problem related to memory management. Let’s describe the problem :-

I have a class like SkeletonAnimation of cocos2d-x library named ProductBody inherited from Node which is used to animate Products(Dragons, Dinos etc). I have another class named FighterAnimation inherited from ProductBody.

I have another class named FightDragon where the dragons do fight against opponent dragons.
In FightDragon class I create two objects of FighterAnimation are deathAnimation and powerAnimation. I have to remove deathAnimation and powerAnimation after the animation sequence done. After that deathAnimation and powerAnimation is created. In this loop I notice that deathAnimation and powerAnimation is altered. This is the problem. I don’t know why this is happening.
My classes are below :-

ProductBody.h

class ProductBody : public Node
{
public :
virtual ~ProductBody();
ProductBody();
static ProductBody* create();
// another several functions here
}

ProductBody.cpp

ProductBody::~ProductBody() {}
ProductBody::ProductBody() {}

ProductBody* ProductBody::create()
{
ProductBody* ret = new ProductBody();
if(ret && ret->init()) {
ret->autorelease();
return ret;
} else {
delete ret;
ret = nullptr;
return nullptr;
}
}

`

FighterAnimation.h

class FighterAnimation: public ProductBody
{
private :
virtual ~FighterAnimation();
FighterAnimation();
static FighterAnimation* create( int product, int mylevel, bool movement);
// another several functions here
}

FighterAnimation.cpp

FighterAnimation::~FighterAnimation() {}
FighterAnimation::FighterAnimation() {}

FighterAnimation* FighterAnimation::create( int product, int mylevel, bool movement)
{
FighterAnimation* ret = new FighterAnimation();
if (ret && ret->init(product, mylevel, movement)) {
ret->autorelease();
return ret;
} else {
delete ret;
ret = nullptr ;
return nullptr ;
}
}

FightDragon.h

class FightDragon : public Node
{
public :
~FightDragon();
FightDragon();
FighterAnimation *deathAnimation;
FighterAnimation *powerAnimation;
void loadAnimation();
}

FightDragon.cpp

FightDragon::~FightDragon() {}
FightDragon::FightDragon() {}

FightDragon* FightDragon::create()
{
FightDragon* ret = new FightDragon();
if(ret && ret->init()) {
ret->autorelease();
return ret;
} else {
delete ret;
ret = nullptr;
return nullptr;
}
}

void FightDragon::loadAnimation()
{
deathAnimation=FighterAnimation::create(8202, ageBaby, false , folderName);
powerAnimation=FighterAnimation::create(7326,ageAdult, false ,folderName);
}

When I check deathAnimation->productid it prints 7326 but should prints 8202 and powerAnimation->productid it prints 8202 but should prints 7326.
In short, these two objects are altered sometimes, I repeat altered sometimes. It means this is not happen all time.
Please help.
Thanks in advance
