Does anyone know how to delete a facebook 'like-button' code from 'EDIT' page of ADOBE CONTRIBUTE?

Hello

I cannot delete the 'LIKE' BUTTON icon from the 'edit' section of the user-interface in ADOBE CONTRIBUTE, can anyone please help?

I can delete anything else from the page but the 'like' icons remain static and cant be moved or deleted, very bizarre, anyone know how to remove them?

Thanks
