Having issues with the links

Good evening!

First of all, I would like to thank you for this plugin. It looks really nice so far.

I am having some issues with links. When I put https:// or https:// in front of a link, I am not able to save the link section. If I remove it (so that the link starts with www.), when a link is clicked on the page, it does not work because it places the link behind the link page at my website. So for example, the link is https://www.example.com and the link page I set up is https://www.test.com/instagram, when you click it, it leads to https://www.test.com/instagram/www.example.com.

This also occurs when I try adding social links.

Am I doing something wrong?

Thanks in advance for your help.
