Im just wondering if anyone has the same problem of double people in the tree - it happened to me when i deleted someone and my whole tree went haywire - had to call the helpline

now i seem to have two people of some of them and if i delete one of the two if seems to remove them both - i thought it was becasue i had a lot of people in my tree but it only started when it reached 200 which isnt a lot when ive seen trees on here with 400+

any help appreciated
