I created a new board and went to "Board Settings" > "Columns and Rows".
I choose "Columns are identified by" = "Type".
Different Types got listed and I changed the name of each Types to fit to my new board.
I didn't know that this would affect other boards, and now other boards are fucked up (especially swim lanes)!!!
I want to change the Type names back to the old ones but I don't remember them unfortunately.
Can I undo my action?
Your help would be very much appreciated!
