In your __str__() method of model Product self.product returns list of names.

class Product(models.Model):
 ...
 def __str__(self):
 return self.product # This returns list of names 

You can either convert self.product to string manually or replace with following one.

class Product(models.Model):
 ...
 def __str__(self):
 return ", ".join(self.product) # This would join list of names with ,
