Are the boards/cards linked in any way?
If they're showing on one board but not the other, that would say to me that they 'live' on the original board and that if you have a Butler command set up, it's not doing what it should.
Cards live in only 1 board, you can move them into another one, or have Butler do this for you, but unless you use Unito (I believe that's the one), they only 'live' in one board.
Does that help at all?
If you had to thrive a new habit during a lockdown, what would it be? Trello
