Multiple Ads on Same Page Behaving Badly

Hi,

I installed your plugin last night. I set up a header banner that displays three ads side by side here. My intent is for each ad position to be associated with a different ad group (different sponsors) and for each group to randomly display an ad from that group only. The result I get is that ads are displayed randomly, but may come from all ad groups, not from the group selected for each ad position.

The code I used:

<div id="banner-ad-container">
<div id="banner-ads-box">
<div class="ads-first"><?php echo dfads( 'groups=-1&orderby=random&container_html=none' );?></div>
<div class="ads"><?php echo dfads( 'groups=26&orderby=random&container_html=none' );?></div>
<div class="ads"><?php echo dfads( 'groups=27&orderby=random&container_html=none' ); ?></div>
</div>
</div>

Thanks in advance for helping me with this.
