Data preview shows but does not scrape

I tried scraping from photography items details from webuy website. I had no issues when I for camcorder ( https://uk.webuy.com/search?categoryIds=951&categoryName=camcorders ), but when I tried other categories such as digital frames ( https://uk.webuy.com/search?categoryIds=848&categoryName=digital-photo-frames ), there are details in data preview but not in scraped available to download as .csv format. Also, when I exported the sitemap for camcorders to cloud.webscraper, it does not scrape any data anymore.

This is my sitemap with multiple start URLs.

{"_id":"cexuk_photography","startUrl":["CeX (UK) : Stock searchparent","multiple":true,"delay":0},{"id":"Model Name","type":"SelectorText","parentSelectors":["parent"],"selector":"h1 a","multiple":false,"regex":"","delay":0},{"id":"Category","type":"SelectorText","parentSelectors":["parent"],"selector":"p","multiple":false,"regex":"","delay":0},{"id":"Sell Price","type":"SelectorText","parentSelectors":["parent"],"selector":".prodPrice > div > div.priceTxt","multiple":false,"regex":"","delay":0},{"id":"Buy Price","type":"SelectorText","parentSelectors":["parent"],"selector":".prodPrice div div div.priceTxt:nth-of-type(1)","multiple":false,"regex":"","delay":0},{"id":"Buy for Voucher Price","type":"SelectorText","parentSelectors":["parent"],"selector":"div.priceTxt:nth-of-type(2)","multiple":false,"regex":"","delay":0}]}

Can you please help me with this? Thank you.
