Go to the menu and set this “https://loudpages.com/login/” as the URL for the log in, if you can’t change it, delete the “Log In” menu item, and add a custom link, with “https://loudpages.com/login/” as the URL and set the name as “Log In”.
This should fix your problem, you then will have to go remove these pages from your Google Search Console so they don’t come up when people search for your site.

when you are on a post and you click on “Log in”, it redirects from that post and creates a link like this
“https://loudpages.com/login/?redirect_to=https%3A%2F%2Floudpages.com%2Fseo%2Fseo-optimized-content-writing-loudpages-com%2F”
These links it creates are been indexed.
What is the url you have in the”Log In” on the menu?

It should still be on Appearance -> Menu, maybe you just have to set the other menu as the one you want to show on your top menu

It seems your login page is been indexed, do you have a redirect set for some pages?
