WP-login page Need Help Please

My WP-login page is not working correctly.

1. After logging out as the admin and logging in a test member, the page redirects to a WP-login page where I need to answer a maths question (see screenshot 1)

2. After completing the answer, it redirects to another login but with the admin credentials, not the test user. (see screenshot 2)

3. Logging here only redirects to the first page with the maths question. I have no idea what is going on.

I have disabled all plugins that are associated with login’s as well as clearing the cache and cookies and it still persists.

Any help would be greatly appreciated.
