It's a combination of being bad at prompting and different expectations from the tool. You expect it to be one shot, and then rewrite things that don't match up to what you want.

Instead I recommend that you use LLMs to fix the problems that they introduced as well, and over time you'll get better at figuring out the parts that the LLM will get confused by. My hunch is that you'll find your descriptions of what to implement were more vague than you thought, and as you iterate, you'll learn to be a lot more specific. Basically, you'll find that your taste was more subjective than you thought and you'll rid yourself of the expectation that the LLM magically understands your taste.
