Hi,
As a SEO recommendation a site should not be accessible from both http and https.
You should add use a redirect rule in your htaccess (assuming you’re on a apache server) file to do it.
Maybe some plugins should do that to but redirecting in the htaccess file is better.
You can google it there is a lot of questions and answers about that.
Once it’s done clear your cache and as the http version of your site will be never accessed by any visitor you will not have this issue anymore.
Best regards
