Hello guys,
I am adding one Card under a certain List, but Trello is multiplying it automatically.
For instance, I am writing "Meeting with designers" under To Do List, but Trello is creating 2 cards with the same task automatically. When I write second task, Trello is creating 3 cards with the same task and so on. Did anyone has the same problem, bug? Or I am doing something wrong.

Thanks in advance.
