Keyword triggering ad from different ad group

Strange!

[SEMblahblah]

When I search for one of my keywords (from ad group A), I see my ad, but its an ad which belongs to another ad group(say B) in another campaign all together. Moreover, this ad group B has all its keywords paused for a while now..so its not like I may have similar keywords in the two ad groups and hence this might have happened!

Just to add to this, the ad group B has zero impressions since yesterday.

Also, the ad that's showing had some issues with the destination url and on a click, it directs to a "page not found" url.
So, ideally, as per Google, this ad should not show at all in the first place, right?

Any explanation for all of this?

I had a similar thing happen to me, in fact, I posted about it [webmasterworld.com]. Never got a real satisfactory answer as to how or why it was happening.
