Login screen redirect does not work after logout unless cache deleted

I have set up my site to use Auth0 to login and it works well. Logout also works. But when I log back in, the redirect to Auth0’s universal login page does not show up. Instead a broken version of the sites login page shows up. If I clear my browser’s cache or start up a page in a new private browser window it works. In the private browser, the broken login page also shows up after a login/logout cycle. You have toe close and reopen the private browser window for the Auth0 universal login screen too show up.
