Problem with A16 inputs 9-16

[jarekD]

when digital input =0v or short with GND then DI=ON
when digital input =12/24v then DI=OFF

Okay, I might not have been clear regarding 12V in my first post.
I tested this with nothing connected to see if inputs 1-8 and 9-16 behave the same when nothing is connected to either of them. They do, the multimeter shows +12V from GND to any input when nothing else is connected.
But with my A16, inputs 9-16 show as ON all the time, with nothing connected, and with the inverted: true flag set in the config.
