BUG: Trello is creating duplicate cards in multiple lanes for no reason. any ideas?

Question

For example, if I create a card in column 1 and move it to column 2, it appears in both. I'm afraid to archive one because I don't know which is most recent or if it's an alias.

Hi @Kimberly Brooks, welcome to the Atlassian Community!

I can't replicate the issue on my end. Could you please check if there is any automation enabled on that board? It's common for cards to be duplicated due to automation. If you don’t find any automation that you've created, it might be helpful to check with other board members to see if they set something up.

Let me know how it goes!
