Hello, thank you for the suggestions!
I checked the register page and it was already set to the default page. I changed it to a different page and back to the default one to see if it would do anything but still had the same issue.
I installed the plugin and the level 1 backtrace resulted in the following:
File: wp-content/plugins/pmpro-buddypress/includes/restrictions.php
Line: #267
Function: wp_redirect
Function Arguments:
array(1) {
[0]=>
string(37) "https://mysite.com/register/"
}
