Copying list and cards missing

[RenoT]

I am trying to copy a list of completed cards as a new list for backup, several times but failed to have the completed cards in the new list, the strange thing is, when I check the Trello boards, seems like both list has exactly same cards, but in Placker shows one list has 213 cards but another one only 101 cards, and this might be the reason caused failure, anyone has the same problem?

Can you check if the Power-Up or the set up of the Power-up mentioned might be causing a problem with copying that list? Can you try copying a list from one board to another without any Power-Ups enabled on those boards to see if you observe the same behavior? If that is the case, let us know at trello.com/contact
