Cards are far ahead than expected?

[Taiel]

Hi, so the thing here is I noticed some of my cards are far ahead than they should, like they split or something like that. I do my reviews and always press the 3 key to mark them as good so I don’t understand why they have different intervals!?

Why does this happen? How do I stop this, is there a way? I want to stop this behavior as soon as possible, before the snow ball begins to road and completely messes up my cards

The graph correctly shows that you’ve pressed Button 3 on all your cards.
The split is to categorize your answers by the types the cards have when they were in different stages, as can be seen from the “Learning”, “Young”, and “Mature” labels under the bars.
