Suspect that there is a bug with the analog read node
attached are two example sketches for you to try!
2019-11-17%2016_40_09-Window|442x248
The bug is that the 4 inputs dispite being listed as A0, A1, A2 and A3 all show roughly the same reading.
Tested this on a Genuine Arduino Micro and a Genuine Uno and a Maker Uno… all the same issue…

Are the inputs floating or connected to any sensor?
oops! 
a0 > pot
A1,a2,a3 floating
tried it with all 4 inputs connected to potentiometers… working ok now (didnt know that the floating inputs would be ~ = to A0… live and learn…
(not very good for fault tolerance …
I expected the input to float to an arbitrary reading, just not to a reading to ~ track A0
again live and learn… (the watch is helpful tool of XOD)
