Cant get the href for some reason

Another head scratcher. Can get each product title and price OK, but cant seem to get the link to the product's own page. Have hacked some HTML extrat with regex which is kind of functional but unweildy. Why isnt this method working, works fine for other websites..?

Url: https://www.sevenoakssoundandvision.co.uk/c-7-Clearance.aspx#pgnum=&sort=

Sitemap:
{"_id":"sevenoaks2","startUrl":["https://www.sevenoakssoundandvision.co.uk/c-7-Clearance.aspx#pgnum=&sort="],"selectors":[{"id":"nextpage","type":"SelectorLink","parentSelectors":["_root","nextpage"],"selector":"div:nth-of-type(3) a.next","multiple":false,"delay":0},{"id":"product","type":"SelectorElement","parentSelectors":["_root","nextpage"],"selector":"li.product","multiple":true,"delay":0},{"id":"productititle","type":"SelectorText","parentSelectors":["product"],"selector":"span.product-name","multiple":false,"regex":"","delay":0},{"id":"price","type":"SelectorText","parentSelectors":["product"],"selector":"span.product-price","multiple":false,"regex":"","delay":0},{"id":"plink","type":"SelectorElementAttribute","parentSelectors":["product"],"selector":"span.image","multiple":false,"extractAttribute":"href","delay":0}]}

Seems straightforward enough with Type: Link, e.g.

{"_id":"forum-sevenoakssoundandvision","startUrl":["https://www.sevenoakssoundandvision.co.uk/c-7-Clearance.aspx#pgnum=&sort="],"selectors":[{"id":"Wrappers","type":"SelectorElement","parentSelectors":["_root"],"selector":".product-box > div","multiple":true,"delay":0},{"id":"Title","type":"SelectorText","parentSelectors":["Wrappers"],"selector":"span.product-name","multiple":false,"regex":"","delay":0},{"id":"Price","type":"SelectorText","parentSelectors":["Wrappers"],"selector":"span.product-price","multiple":false,"regex":"","delay":0},{"id":"Link","type":"SelectorLink","parentSelectors":["Wrappers"],"selector":".title-bar a","multiple":false,"delay":0}]}
