Deck vulnerabilities

I'm having a problem. I have several decks that I've categorized, but I can't practice each deck individually. Each deck contains 100 cards, but when I click "Practice All Deck," it only shows 6 or 70 cards. I hope you can see my problem and help me solve it. Thank you.

Sorry I only saw your reply now. The problem has been solved. The reason is that there were duplicate words in two word lists. When I reviewed one of the lists separately, the repeated words didn’t show up. I hid the duplicate words first and then added them, which fixed the issue.
