Wordfence dashboard link generates a double URL in the path

In my Wordfence Dashboard I have an issue notification and when I click on this notifcation ideally it should take me to the issue page with the details .. instead it takes me to the login page which is fine but on providing the login details it doesn't do anything.. it just stays on the login page..
I thought it was Wordfence issue and I created a ticket for this on their site and they recreated the issue and found that the login path being created had a double slash in the URL and they suggested that there was an issue in the sites rewrites part.. here's their mail to me..

Hi Alim,?
?I just looked at this and can recreate the problem. I see the possibility you've got some misconfiguration going on:?
1) A sign some rewrites might not be correct with the doubling of the // in the url like:
If I use the link in proper form https://fourplusmedia.com/wp-admin/network/admin.php?page=WordfenceScan the logout issue does not happen.

Please advise
