Copies of page with index “?post=1”

[yuriy.lutchenko]

Hey, everybody.
For several years I can not solve the problem, the thing is that Prestashop, and perhaps some module creates a duplicate page with the ending “?post=1”. 

For example, there is a page: 
https://www.probag.com.ua/uk/backpacks-fjallraven/34489-fjallraven-vardag-16-stone-grey.html
and its copy : 
https://www.probag.com.ua/uk/backpacks-fjallraven/34489-fjallraven-vardag-16-stone-grey.html?post=1

For this reason, in Google Search Console there is a variant of the page with the canonical tag.  The following pages are not indexed by Google and do not appear in search results.

Please help or tell me where to look. I will be grateful for any option.
