Scraped products not working to display sale products, woocommerce filters

I have a product platform that I am scraping from other websites, everything works fine but when I want to create carousel of offers or show products on sale, it does not consider the products, I need an expert in scraping and woocommerce ... This error affects price offer and also filters like price or others. I also have product uploaded manually and they have no problems, also I just took a scraped product I added a sale price and it did appear on the carousel ...
