Analogue pins A0-A5 are ok, A6 does nothing, A7 is responding to input that A6 should be receiving? 
(I’ve been using 8x “Value Display” widgets to read the 8x analogue channels, also 8x button widgets to switch on 8x LEDs! (I’m not very adventurous I know! 
))
(I set up 8x Pots in a row on a PCB for testing purposes, double checked and there all working fine! 
So I’m guessing its in the Code (I’m using the ENC28J60 Example))
I had a look in the “Arduino-Nano.json” (Shown Below) Don’t know why I did that!? 
but I noticed that A5 and A6 are mapped to the same number “19”. is that correct?
I’ve had no other problems with my setup, it all works fine
