How do I stop Trello from making a new list when it's meant to go into a particular assigned list?

[Andrew Ehrensperger]

Whenever I add the 'Please Review' label to one of my cards, it's meant to go into the "Active Requests" list. It doesn't go into the "Active Tasks" list, instead, it creates a new list with the same name, even though there is nothing in the Automation which asks for it to do so. It also has a different name for some reason as "Active Requests". No idea how this can be happening, if there isn't an Automation asking it to do that, only for the card to be moved to an existing list.

Hi Andrew, 

Welcome to the Atlassian Community! 

I've just tried reproducing this issue on my account and it appears if you type in the title of a list that doesn't exist on a board, a simple rule like "when the red label is added to a card, move the card to the bottom of list "List" can indeed create a new list on your board. 

I'd encourage you to make sure you choose the destination list from the options you see when creating a rule instead of typing in the title yourself (it might be you're pasting in an extra space that doesn't match the current list's title): 

Also, it looks like there are several similar rules running on your board. Since Automation rules are linked to the account they were created on, I'd encourage you to check with other board members that they don't run the same rules as you do. 

Hope this helps!
