Most of my Trello cards don't need checklists. I used to add them manually as needed. Now, whenever I create a new card on the website, it automatically adds a blank checklist called "Checklist". I've searched through the settings but I can't see any way of controlling this behaviour. The mobile app still doesn't add checklists unless you add them yourself.
At the moment I have to delete the checklist from every card when I create it. Is there a way to revert to the old behaviour?
EDIT 1
I've just added a card to my work Trello, and it didn't add a checklist. The difference between my work and personal Trellos is that I had set up my personal one with a team, but not my work one. I've just created a team for my work Trello and added the board to it, but I don't have a need to create another card just yet. I'll see what happens next time.
