Card 4 should be either 19.2 or 28.2 not both (although not sure this makes a difference in the end).
Do you know which wire goes to which LNB?
Your setup should look like one tuner set to 19.2 and only channels on 19.2 mapped to this. Your other tuner should be set to 28.2 and only channels on 28.2 mapped to this.
It looks like you have a mix of both (which will cause other issues with tuning).
As above, easiest way is to pick a transponder and do an advanced scan, you can check the results against.

which would prove which tuner is connected to which LNB. If they both pickup 28.2 then there is something wrong with the wiring....
