How to remove hidden link?

Hi,

My wordpress template is causing all of my pages to have one hidden link. The format of the hidden link is the URL itself with the addition of the following string (/%C2%A0) at the end of each URL. I can’t trace the main reason for this hidden link. Please help me out to find it. My site is https://www.lugaluda.com.

By the way, I use Lynxx Viewer to check for hidden links.

Thanks in advance…
