[Plugin: Simple Ads Manager] Exclusions not working

I’ve got the plugin running on our publishing site. Great plugin

We’d like to do some fine tuning on what ads appear on the single posts, but I cannot seem to make it work correctly. Here are the scenarios…

Set up:
We’ve three ad zones basically, the header, the content, and the sidebar. We’ve got multiple ad places set up with multiple ads.

Scenario 1:
We’d like to be able to display ads from advertiser ‘A’ in the content and sidebar, and have no ad displayed in the header.

I’ve created a patch ad for the header that is essentially a blank image. I’ve tried setting it as both a link to an image, and an image tag in the HTML option.

We’ve got the header ads set up to be excluded from specific post IDs and posts with certain Tags.

We cannot get the patch to show up in these instances. An ad always shows up.

Scenario 2:
We’ve got the sidebar set up with a few ads. All but one of the ads is set up to be excluded on certain page IDs and certain posts with specific Tags.

When we go to those pages, all the ads show up (in rotation), even though they’ve been excluded.

It seems that the exclusion functionality is not working on single posts.

What could I be missing?
