This is still the case with the FG as I recall.

To try to explain this I have come up with this below as an example.

Button one is resistance 10
Button two is resistance 20
Button three is resistance 30
Button four is resistance 40
Button five is resistance 50.

So if you have a resistance on any of the other connections it will change the buttons. So lets say there is a 10 resistance in one of the other connectors.

So button one is now resistance 20 (10 + 10) so now working as button 2
Button two is now resistance 30 (20 + 10) so now working as button 3
Button three is now resistance 40 (30 + 10) so now working as button 4
Button four is now resistance 50 (40 + 10) so now working as button 5
Etc.

So if the buttons have changed around, the problem is likely with something other than the buttons themselves, so the steering wheel contact etc.
