potion\\inventory bug? (The Witcher 3: Wild Hunt)

in short, he created a tavern bomb (or whatever it's called) for nests, destroyed the nests, decided to create more such bombs for the future, I have all the ingredients with my head, but it's funny when I go into alchemy and try to create a bomb again, it says that I have such an object has already!! although I have 0 bombs, but I have all the ingredients for it, where do I hit my head on the wall, what am I doing wrong?
