My cards are disappearing

Recently I went onto my Anki and it looked like some of my cards had disappeared because the “due” and “new” columns showed grey zeros in some of my decks. When I click on browse and look through my cards they are all there. I thought that maybe I had completed those cards and that they would show up in a few days. But they have not reappeared to complete in months and I am getting worried because I cannot test myself unless I go on browse and look through them that way. Please help!

Does this help to understand the situation?

What does it say the info history of these cards?
