Used to work great, now not so much.

When I used this before, it worked. Now it doesnt. It didnt recognize a lot of duplicates I had. Okay, no problem, I will manually merge them. Except that doesnt work either! If you select which contacts to merge, it jumps to you a merged contact, which looks great. Then you click "Done" and nothing happens! Im disappointed in whatever changed to make this not work.
