You used Login Web as show a page in navigation instead of select create object and entity which was used in that page.

The issue itself 

Good day

If you are creating a login page for your application, then do not add dataviews to it and just allow the Anonymous user access to the page, do not add it to your navigation menu. However if you want to have specific entities on the page you will need create microflows on the dataviews of the page. 

Also dont use page parameters on your first page.
