My website is using a 3rd party filter system which is universal filter. As a result, different category product pages are not indexed as Google Search Console sees it as a (duplicate) Alternate page with proper canonical tag. Please find attached screenshot for Google Search Console error.
So for example, Biodegradable products is seen as an alternate page of the main category page
https://www.skp.com.sg/food-packaging-all?category=Biodegradable
https://www.skp.com.sg/food-packaging-all

Can someone explain how do i make Google Search Console to index these (supposedly duplicate/alternate) pages? (I believe this is hurting my SEO keywords ranking)
Is this caused by AJAX loading, if so can how can i solve this while enabling AJAX loading?
(Can this be solved by adding a dynamic JSON-LD to each category filter?)
