Not Showing ads on some posts

Hi,

I’m having a really strange problem with the ad inserter plugin. The sidebar widget works on everything, so that’s no problem. When it comes to the ads between paragraphs on the blog posts, it’s not showing on some posts. To break it down simple, I have different categories on my blog… “Make Money” category, ads show on every single post. “Personal development” category, ads show on every single post. I have a category labelled “blogging, and for some reason, ads are not showing on pretty much every single post in this category other than I think 2 posts in this category which are fine. Any ideas?
