Why GSC is showing external links as millions for GEO target website?

[Rajesh.Prajapati]

Main website xyz.com have only 10K external links while geo target sites xyz.com/ca (which is for Canada) have 100K external links in Google Search Console. Mostly links which are showing as external links for xyz.com/ca are from xyz.com
Ex.-
External links for xyz.com/ca -
xyz.com/contact-us
xyz.com/product
xyz.com/category

Is it possible? or missed any technique to implement in geo target sites.
