Canonical Link false for DataObjects

[Gregor-Agnes]

Hi, I created a dataobject for countries, having a list /countries and a country view /countries/albania
Also enabled the extension for the model. I get the additinal tabs in the backend.

Country:
  extensions:
    - CyberDuck\SEO\Model\Extension\SeoExtension

But the canonical meta tag does not change: It is example.tld/countries in either case. It should be example.tld/countries/albania in the country view (just like the address in the address bar of the browser). But it isn't.
Did I miss something?
