Price Slider not working in Magento 2 after installing


I am not a developer but I am posting it on behalf of my devs who are based in India. We installed the Algolia plugin on the Magento 2.2 installation but the pricing slider has disappeared. I am sharing the screenshot of how it looks front end.

Can anyone please kindly help so I can share the guidance with them for it to be fixed kindly?

I am also attaching a screenshot of how the pricing looks at the Algolia backend.

Many thanks
