Redirects to Incorrect Page (not login)

Hello,
Instead of being redirected to the login page, members trying to access private content are redirected to the welcome page, from which they need to click another link to log in. Once they are logged in, they are directed to the home page, not the content from the linked private page.
I think the issue may be the extra step (clicking from welcome to login page), but I’m not sure. Is there a way for me to find out if this is in fact the issue? If it is the problem, how can I fix it?
Thanks.
