SRx1 Auto Protocol

[techniplex]

I am using the SRx1 V4 smart receiver with FPP 7.3.5 and setting A-F for auto protocol will not generate outputs. If I set FPP to V1 and select 1-3 then I get outputs and the same with V2 protocol and setting 4-9. 

I am guessing normal behavior but in testing port number only the A reciever has the white lights for the port number followed by R-G-B, while subsequent recievers do not show the port number with white light designation. Seems like subsequent recievers should have a different solid color for A, B, C, etc
