Extract sizes and prices, can't find the way, please help

How to?
#1

Describe the problem.
The page seems to timeout before extracting the data. I'm trying to scrap the whole site for a specific brand "Oriental Weavers". Ideally would get Name and sizes with prices (normally, a regular price, a was price and a now price).
Url: https://www.modern-rugs.co.uk/tabriz-2060y-cream-beige-rug (this is one of the rug collections, here's another one with more sizes: https://www.modern-rugs.co.uk/search/go?ts=custom&w=greek-key-flatweave)

Sitemap:
{"_id":"mr-test","startUrl":["https://www.modern-rugs.co.uk/search/go?ts=custom&w=tabriz"],"selectors":[{"id":"scroll","type":"SelectorElementScroll","parentSelectors":["_root"],"selector":"a.product-item-link","multiple":false,"delay":"500"},{"id":"links","type":"SelectorLink","parentSelectors":["_root","scroll"],"selector":"a.product-item-link","multiple":true,"delay":""},{"id":"name","type":"SelectorText","parentSelectors":["links"],"selector":"h1.page-title","multiple":false,"regex":"","delay":""},{"id":"data","type":"SelectorText","parentSelectors":["links"],"selector":"div.swatch-attribute-options","multiple":false,"regex":"","delay":""}]}

Setting a longer page load delay when scraping starts should work
