I need help again, really don't get what's going on here.
When grouping some objects on a card, they simply disappear from the card. I can only "see" them in the Project Browser. The layer of the card itself is 3 and for some reason I can't change it to 4 or higher. The layers of one of the vanished groups and the two objects it contains (label and field) are 5, 6 and 7. The objects are all set to visible. One of the groups does not disappear but I can't spot any significant difference between this one and all the disappeared ones
