I have tried everything, it just won’t work…
As it is not vital, i am giving up on this one. Also, i am pretty sure it is an Appsheet bug, as i can get all the other views display a map from the addresses.
As @Aurelien notes, Card view types are buggy: they have never fully supported all column types. In my own experience, Card views sometimes behave differently for different tables for no apparent reason. I recommend avoiding Card views. If you cant, be sure to test them well for each particular use.
