Using the exact same note type just days ago I entered about 40 cards. I see for each card just Card 1, Card 1, Card 1 with the occasional Cloze for the few Clozes that I needed. But, each time it’s just a SINGLE card. One card for one note.
Suddenly, now, each time I select the Basic note type…the system is creating TWO cards each time.
Ah! I feel confused. In the documentation it says:
“If you have modified the Basic card template to add an unwanted reverse direction, you can modify it back instead:”
As far as I know, I didn’t do that. BUT! Fair enough - it’s happening, so I guess that’s the case.
But, here’s where things get confusing. Right after that it says:
Edit a card Click the ‘Cards’ button You will see one or more tabs at the top representing each card type that will be created. Locate the card type you don’t want, click the Options button, and remove the unwanted card template.
The id after Basic- is appended by Anki to newly added notetypes when a notetype with the same name already exists in the collection, because there mustn’t be two notetypes with the same name.
As to what caused the creation of a new Basic notetype after you’ve undone your template edit, I don’t know. We’ll have to find a way to reproduce the issue before it can be fixed.
