Membership Plugin Redirect Glitch

I have found a minor glitch in the membership plugin that I think is related to the . i have a section of a site that is using the plugin, and all of the files live in a single folder... /members/

If I not currently logged in and I try to load the section by typing the URL "http://www.domain.com/members/" without including "index.php" at the end, it redirects me back one folder level to this url: http://www.domain.com/login.php?loginRequired=1

But if I include "index.php" it works fine. And without the membership plugin the index file loads as it should.

My Global URLs are set like this:
$GLOBALS['WEBSITE_LOGIN_LOGIN_FORM_URL'] = 'login.php';
$GLOBALS['WEBSITE_LOGIN_SIGNUP_URL'] = 'signup.php';
$GLOBALS['WEBSITE_LOGIN_REMINDER_URL'] = 'reminder.php';
$GLOBALS['WEBSITE_LOGIN_PROFILE_URL'] = 'profile.php';
$GLOBALS['WEBSITE_LOGIN_POST_LOGIN_URL'] = 'index.php';
$GLOBALS['WEBSITE_LOGIN_POST_LOGOFF_URL'] = 'login.php';
