Issue on social share url return

[noxalbum]

Hi. I'm using your theme.

Unfortunately, I have faced a problem.
I activated social share, but when I clicked the button, broken(?) url is returned.
For example: at "www.example.com/Example", when clicked, the wrong URL "www.example.comwww.example.com/Example" is shared.

is this an issue of this theme, or could I fix it by modifying my site's setting?
