In post ads not showing up in assigned categories

Actually, this is not about newsletter; it's about In-Post adsm but that is not showing up in your drop down!

The problem that I am having is that the couple ads that I have up as tests are not showing up in their assigned categories. They are showing up elsewhere. I have cleared the cache in wordpress and also in my site.

Some of the "Uncategorized" blog posts have ads showing up and it seems that all of the "Pearls" category does. But neither "First Explorations" or "Settling In" (/immigration-and-visitor-information/) seem to have any ads working - and these are the only two that I have assigned.
