Hello,
1) Please, export options (Theme Options > Import/Export > Options > download export file) and share us with link to this file. We’ll import your options and after that will be able to send you the correct one to fix the problem that you have.
2) If you want to replace existing share icons for the post/product you can use either that third-party plugin and disable our share icons (Theme Options > General > Share buttons) or you can customize then using custom CSS to change the styles.
Regards
