https://www.jamestowndistributors.com/product/epoxy-and-adhesives?page=2&resultsPerPage=16 is the paginated URL of the category https://www.jamestowndistributors.com/product/epoxy-and-adhesives/.

Can I remove the &resultsPerPage= variation from the canonical without it causing an issue? Even though the actual page URL has that parameter?

The Moz bot user agent detection settings are able to read Universal, but the Single Page Application (SPA) version partially loads on the website before Universal. Because of this, Moz (and possibly search engines) think we have massive duplicate content issues. For example, the crawl report said a particular product page (which has about 1,000 words) has 33,000 words and has duplicate content with over 300 other pages. This makes me believe it's only picking up the SPA version. Has anyone come across this, and what would be the fix?
