Very often when I compare matches in my tree and other trees the box for the person is empty and contains only the word <Private> even if it's a person born 1730!!!! Why is that?

Also people tell me that my tree has those boxes! s far as I know I have NOT blocked any persons or blocked any information to be seen, or.......... have I missed something?

I'm having the same issue. Here no 38  Maren Pedersdtr has only <private> relatives:  http://www.myheritage.no/FP/tree-matches.php?s=128288961&familyTreeID=1&targetFamilyTreeID=17&targetSiteID=115007492&reviewMode=pending

But if I go into tree comparison I get up all of her relatives with full names. http://www.myheritage.no/FP/review-match.php?s=128288961&familyTreeID=1&individualID=1000747&targetSiteID=115007492&targetTreeID=17&targetIndividualID=17012467&comingFrom=treeMatches&listType=toConfirm&mode=compareTrees

 As you maybe can see the persons have been dead for quite some time.
