Non-Indexable and Canonicalised status to the majority of eshop products is this normal?

[Kosram]

I run the screaming frog program and i saw that the majority of our product pages are non indexable and canonicalised. I wanted to ask if this is normal or it is a big fault of our developer? Can i change the canonicalised from prestashop back office or from files?

 

Thank you in advance.
