When I review the card, all the items to choose the re-study time whether easy or hard are displayed 3 days. This only happens with this deck. I have edited the learning options, but still the same. What I need to do? What is wrong with this set of cards?
My guess is you have changed the ‘maximum interval’ at the bottom of that page.
You have multiple deck presets. If you check the options for the card you’re looking at, you should see it has the maximum interval set to 3 days.
Thankiu for your help. I updated a new version of Anki and this mistake is gone.
