Unwanted duplicate product page

Hello,
To start I would like to say that I know very little about html, php, etc. and I am not sure what version of wordpress we are using.

Now that I’ve made it more challenging, here is the problem.

When we googled “RE-3010 Meditek”, this was the link that showed https://www.mediteksurgical.com/products-page/seating/re-3010/re-3010-2/.

We’re not sure where this came from. When we click on it, it goes to a product page that has three pictures of the product in the footer and shows https://www.mediteksurgical.com/products-page/seating/re-3010/re-3010-2/ as the url, although it should be https://www.mediteksurgical.com/products-page/seating/re-3010/ (without the re-3010-2).

Even the meta description, we don’t know where that came from.

There are a few more products like this. Does anyone know what is going on? I would appreciate any help very much.
