Card count mismatch (99 shown, 78 exported)

Hi Memo team,

I noticed that one of my flashcard decks shows 99 items in Memo, but when I export it as an Anki (.apkg) deck, only 78 cards are included. I also only see 78 flashcards in the deck.

Could you please clarify why the deck displays 99 items? Is this a display bug, or are some items not being exported?

I can provide the deck link or screenshots if needed.

Thank you.
