Adverts on posts and pages

I just switched from Game Press to Game Press Pro and even though I have only input advert code into the ‘Ad space #1’ box, I am getting 2/3 advert boxes on my game review posts and normal posts. Is there any way to take these advert boxes away? I really only want adverts on my home page and not on my posts.
An example of my problem can be seen here. https://thejuniorsoccerportal.info/game-review/lfa-cup-final-sheriff-yc-2-1-kilbarrack-utd-match-report/
