OK, I now see that this pluging simply puts the “like” thumb in every post even without adding the shortcode to the post. That’s how I got 2. One appropriately placed, the other in the default place. sigh…
Is there a way to place the shortcode and “like thumb” where it’s desired on the page ? My posts are formatted and the thumb looks odd stuck all the way to the left margin. Ideally I can place the “like” as desired, and omit the default “after post” one.
