Hi @liang,
1. We’ve added the Active Product Filters widget to Shop Sidebar for you, it will also include the clear/reset filters button: https://prnt.sc/N_eYPDuOCMKF
2. Since the filter is using the ajax request, it means you will always stay at shop page. The Canonical link is still the original /shop/.
3. The issue with the “explanation section” from the shop page appearing on the product category pages may be due to how the content is being displayed across templates. We can help you modify the template structure so that the explanation section only appears on the shop page and not on individual category pages.
To redirect all users to the category archive pages, we suggest you to replace the Filter products by categories widget with Product categories widget: https://prnt.sc/xpQo4LH95Ix1
