The double instance of addthis because, you have used addthis in template1 and template2. Goto WP Socializer admin page. Click the “Placement” tab. Under the template 1, remove the code “{addthis-bt}” and save it. Thats all.

You can disable addthis on specific pages also. When you are editing a particular post, you will find option on the right bottom to disable the buttons on that page.
