Using scrapy they scrape incomplete data

I have an script done by myself that is not getting all data. If the pages have a total of 870 items, it's getting about 700, I think it´s something relates to the user agent or delay of rendering...I attached the script so u can see it. what the problem they give me incomplete data Thank in advance
