Linkedin Button opens up Twitter

hello,
I am using the theme Socha on my website and have recently noticed that the linkedin button to share articles at the bottom of my post is now somehow linked to twitter.
I have tried looking through all the options of the admin site to see how to modify this, but was unsuccessful.
I have no specific plugin to do that, so my guess is that it’s in wordpress or in the theme, but I haven’t been able to locate it.
could someone please help me out?

Thanks in advance
