After reading your post, I looked at my circles (there are four - 2 couples).
I have always had people in my circles that are not a match to me, but to others in the circle. There are several of those, however, that used to be matches to me, but got taken away when the changes of 2014 took place.
The 1st storyline that I looked at has bad info. It speaks of a 2nd marriage, two years after the 1st, 3 states away. No 2nd spouse named. So, I looked at all the trees in the circles & none have a 2nd husband, none showed her living in the other state. I can't see where that info came from. It certainly doesn't give me any hope for the future of AncestryDNA circles or the new web site design with the new family stories that they seem to want to insert in our trees.
As for the missing number of people in the circles, it is now on the page of the ancestor circle, rather than the home page where it was more useful. Ancestry just cannot seem to miss an opportunity to fix what isn't broken.
