Adsense Problem

This is a very strange issue …

I’ve manually placed some ads on my blog (rather then using a plugin). There are a lot of posts which display no ads. Thinking this is due to content I ignore this for a while until I noticed this …

when I view a post like this one … https://thebvs.com/blog/?p=114 it does not show any ads … however, the same post does show ads if you ad the following to the url &preview=true … like this https://thebvs.com/blog/?p=114&preview=true

I noticed this when I preview posts (draft) and it showed ads then after being published, the ads were no longer displayed. I can do this with any post I’ve seen thus far, however, some do show ads without the addition to the url.

Any clue? I sure don’t!
