LAYERED NAVIGATION issues

Hi, 

I use layered navigation on my Magento 2.3.6 store + Porto theme, Layered navigation version: 1.10.11 , WeSupply Toolbox: 1.10.17.

Unfortunately remove filter button (x) don't work with Ajax disabled.

If I enable Ajax, remove button work, but, after I have applied some filters, click on product from list don't open product detail but redirect to 404 error (but link to product page is correct!)

Website is https://www.prochet1861.com

Please someone can help me?

Thank you!
