[Plugin: Easy AdSenser] sidebar issues

I have updated to your latest version it has some very usefull features but it will not prioritise the side bar no matter what I do it insists on placing an adsense in the first and second post leaving the sidebar blank. when I click on “more” and go to post page where there is of course only one post then the sidebar kicks in.Any ideas?
