You have no mons attached to your GamePress account.
Connecting directly to your PoGo account is against the ToS, so it will import from a list you maintain on the site for yourself.
Click on 'My Account' at the top of the page and set up some mons you want imported..alternatively, click on some one else's user name in the Q&A, and it will take you to their profile so and you can see some of their mons ;-)
EDIT
Add your mons here...
