Scraper won't select dropdown content

Describe the problem.
I followed the video tutorial about multiple dropdown selectors. any idea why this sitemap doesn't produce any scrape results ?

Url: Nylon Check Chain Dog Collar

Sitemap:
{"_id":"ancolnew","startUrl":["https://www.ancol.co.uk/dog/dog-walk/dog-walk-collars/dog-walk-collars-nylon/nylon-check-chain-collar-black-25-35cm-size-1-2/"],"selectors":[{"id":"product-wrapper-one","type":"SelectorElementClick","parentSelectors":["_root"],"selector":"body ","multiple":true,"delay":2000,"clickElementSelector":"li:nth-of-type(1) select option","clickType":"clickOnce","discardInitialElements":"do-not-discard","clickElementUniquenessType":"uniqueHTMLText"},{"id":"produc-wrapper-two","type":"SelectorElementClick","parentSelectors":["product-wrapper-one"],"selector":"parent","multiple":true,"delay":2000,"clickElementSelector":"li:nth-of-type(2) select option","clickType":"clickOnce","discardInitialElements":"do-not-discard","clickElementUniquenessType":"uniqueHTMLText"},{"id":"name","type":"SelectorText","parentSelectors":["produc-wrapper-two"],"selector":"h1","multiple":false,"regex":"","delay":0},{"id":"supcode","type":"SelectorText","parentSelectors":["produc-wrapper-two"],"selector":".ItemCode strong","multiple":false,"regex":"","delay":0}]}

@Lmac

Hi, It doesn't work because the page is reloaded and each of the variations is probably considered a unique product.

ah does web scraper not support that kind of dropdown ?

@Lmac Element-click won't work in this case.

thanks any ideas what the correct way would be to follow the links.

By the size and color.
