It seems a lot of people have been having this problem since the progression update. There was a change in how cards were "equipped" and "unequipped" at the time the progression changed. This change was just mildly annoying to most of us, since it was a 100% unnecessary change and complicated card management a bit, but to those running into this problem with wrong cards, the change has been disastrous. Basically, EA absolutely needs to change back the way cards are managed, or it will just keep happening. It is completely ridiculous the steps that people need to go through, all the baloney about cloud saves and whatnot, to solve what is a bug that EA introduced into the game during the update. And it sounds like "support" is really not up-to-date on the problems that are occurring in the game, like there is a big lack of internal communication at EA, which is not a good business practice.
