When i'm going to import in Pleco my selfmade flashcard (italian definitions, from the textbook I use to study hanyu), i have a strange situation: Pleco imports my cards not in total but only some of they (i.e. a category has originally 150 flashcards but i can see only 120 of there), but if i try to create a new flashcard of the carachters that are not imported, he say me that is a duplicate.
Some card could be hidden? or there is some other problem?
