I'm having trouble creating multiple posts

I tried using chat GPT 3.5 to write many articles. I use the same prompt for them. However, the second and subsequent articles never reach the same quality as the first article.
The first published article is 1000 words, has meta description, and keyword filtering. This makes me satisfied

But

The second article onwards can only be 500 - 700 words, no meta description, no keyword filtering.

Can you tell me the reason and how to fix it?
Thanks all

If you use the same prompt for each post, the model will most likely start repeating itself, causing shorter and less useful articles.
