ALP heads in order?

I have had my 3 head front ALP system installed for a few months now, been working great. I just updated to the new firmware. I had one question about placement of the heads. I know you supposed to have your heads in order F1, F2, F3, but when I updated my firmware I just wanted to check and I ran the detect sensor option. It read off to me F3, F2, F1. I know the middle head supposed to go in the F2 slot, does it matter if the far left head is in the F1 or F2 slot? It was my understanding it supposed to go F1-Left,F2-Middle, F3-Right. So shouldn't I be hearing F1, F2, F3 ? If this is the case why am I getting the notification in reverse ? Thanks for your guys help in advance !

Does not matter from left to right or right to left... As long as the center head is the middle and its connected to the F2 port.

Thanks as always Tom !
