This is actually not a problem of my module, it is generic problem of prestashop and/or theme. It is the theme that should implement canonical tags for product page.

My module implements canonical tags for All review pages because this is the page it owns. It can't, however, adds these canonical tags to Product page, because it doesn't own it. Adding these tags might even break stuff for some users - revws module has no knowledge if these tags are already there or not. And duplicate tags can be even worse then no tags at all.

In short - you need to modify your theme and add canonical tags there. It looks like this:

<link rel='canonical' href='https://canonical-url-to-product.html' >

Alternatively, you can purchase some third party module that does this for you. There are plenty
