Carole, you haven't finished processing the suggested matches. Apparently, you skipped over suggestions associated with private or unlisted profiles on WikiTree. If you can't tell whether the person is a match or not, due to privacy, I suggest that you mark the suggested match as "match" for now (you can change this later) so you can finish up ALL of the suggested matches.
Once you have finished all of the suggested matches, you will suddenly see lots of ADD buttons in GEDCOMpare. Then go to a profile (maybe yourself) for someone you know well who has a match in WikiTree, open the COMPARE screen, and start ADDing the profiles for your starting person's first-degree relatives. (But please note that GEDCOMpare works best if you add a person's parents and spouse(s) before you add siblings and children.) Once you start doing that, I think you'll see that this can go pretty efficiently -- you won't be manually adding each individual profile, but you will be reviewing (and possibly tweaking) the data so you like the content of the profile before you finish importing it.
Meanwhile, you can send messages to the managers of those mysterious private profiles to see if they are the same people you have in your tree, and (if so) ask for trusted list permission for the profiles.
