I'm currently adding my collection to 2014 Baseball Topps Mini Main Set. There should be 660 cards in the set # 1-661 (no card #7). However, there are over 100 cards missing from the set. When I go to add them manually, I get a message saying the card may already exist and if I want to add it to my collection. I add it but then when I search for it, the card cannot be found. I even tried importing the entire checklist again, but I cannot view the 100+ missing cards. How do I get past this?
