Filter Mirrored Cards

[Dieter Kors]

Hi,

We have an Trello board that only contains mirrored cards. 

Our multiple users can't rely on filtering the 150+ cards to find the ones assigned to them. 

So when I filter by a specific member, the not all mirrored cards appear. One user has 23 cards assigned but sees randomly 3, 8 or 9 cards.

There's also a card which only appears when you mirror it twice; the mirrored card appears in 2 lists.

Very weird behaviour and disastrous for our workflow.

Can you fix this?
